Introduction

Running the Axiom™ 2.0 Assay 24-Array Format Manual Workflow requires the following sets of steps:

1. Genomic DNA preparation, described in the Axiom™ 2.0 gDNA Sample Preparation Quick Reference (Pub. No. MAN0017720), theAxiom™ gDNA Sample Prep for Genome-Wide BOS 1 Array Plate Quick Reference (Pub. No. 702975), Chapter 2 in the Axiom™ 2.0Assay 24-Array Format Manual Workflow User Guide (Pub No. 703335), or Chapter 2 in Section 1, in the Axiom™ Microbiome AssayProtocol in the Axiom™ Microbiome Solution User Guide (Pub. No. 703408).

2. Manual target preparation of the samples, described in this document.

3. Array processing, described in GeneTitan™ MC Protocol for Axiom™ Array Plate Processing Quick Reference (Pub. No.MAN0017718).

IMPORTANT! This document contains an abbreviated set of instructions used to perform target preparation. Carefully read all theinstructions in the target preparation chapter Axiom

™ 2.0 Assay 24-Array Format Manual Workflow User Guide (Pub. No. 703335) before

performing manual target preparation.

Note: Array handling and processing protocols still require the use of a GeneTitan™ MC Instrument, as described in Chapter 5, Array

Processing with the GeneTitan™ Multi-Channel (MC) Instrument in the Axiom

™ 2.0 Assay 24-Array Format Manual Workflow User Guide.

Assay notes• This manual assay format allows the user to run the Axiom™ 2.0 Assay for 24 samples 4 times using 1 Axiom™ 2.0 Reagent Kit 4x24

Reactions (Cat. No. 902798) or 1 Axiom™ Microbiome Reagent Kit 4x24 Reactions (Cat. No. 902910). All samples are processed inColumns 5, 7, and 9.

• This manual assay uses disposable divided reservoirs with a “trough-within-a-trough” design, which maximizes the amount of liquidaccessible to pipette tips when using small amounts of reagent. During the assay, dispense reagents into either the 8-channel,4-channel, or both sides, as instructed.

• We recommend that you prepare your genomic DNA sample plate in a clean room.

• Remove seals from plates carefully and discard used seals. Do not reuse seals.

• Use 8-channel pipettes for all sample transfers and additions of reagents and master mixes to the samples and GeneTitan™ trays.

• Change pipette tips after each sample transfer or addition to the samples.

• Unless otherwise specified, all reagent modules are from the Axiom™ 2.0 Reagent Kit 4x24 Reactions or Axiom™ Microbiome ReagentKit 4x24 Reactions. See Chapter 4 of the Axiom™ 2.0 Assay 24-Array Format Manual Workflow User Guide (Pub. No. 703335) for acomplete list of equipment and consumables required for each stage.

Freeze or proceed to Stage 4At this point you can:

• Proceed to “Stage 4—Denaturation and hybridization” on page 13, or

• Store the hybridization-ready samples at –20°C.


Stage 4—Denaturation and hybridization

Prepare for Stage 4

Supplies required

• Reagents from the Axiom™ 2.0 Reagent Kit 4x24 Reactions or Axiom™ Microbiome Reagent Kit 4x24 Reactions, Module 3, WashBuffer A (Part No. 901446), Wash Buffer B (Part No. 901447), Axiom™ Water (Part No. 901578).

• Axiom™ 24-array plate in a protective base.

• Hybridization tray from the Axiom™ GeneTitan™ Consumables Kit (Cat. No. 901606)

Instruments and setup

• GeneTitan™ MC Instrument

• Approved thermal cycler.– Must be programmed with the Axiom™ 2.0 Denature protocol of 95°C for 10 minutes; 48°C for 3 minutes; 48°C for hold.

– Use the heated lid option when setting up or running protocols.

• Hybridization-ready samples in plate appropriate to the thermal cycler model used.

• 96-well metal chamber pre-heated in a 48°C oven

CAUTION! Some of the steps of this stage should be performed under a fume hood.

Prepare the hybridization-ready samples stored at –20°C

1. Warm up the Hyb-Ready Plate at room temperature for 5 minutes.

It is not necessary to equilibrate the plate for a longer duration.

2. Ensure sure that the Hyb-Ready Plate is sealed well. If the plate is not sealed well:

a. Centrifuge the plate, then carefully remove the old seal.

b. If condensation is on the top of the plate, blot dry gently with a laboratory tissue.

c. Use a fresh seal to tightly reseal the plate.

3. Vortex the Hyb-Ready Plate briefly, then centrifuge at 1,000 rpm for 30 seconds.

4. Place the Hyb-Ready Plate at room temperature.

Prepare the GeneTitan™ MC Instrument and denature the hybridization-ready sample plate

1. Warm up the array plate on the bench top for a minimum of 25 minutes before setting up hybridization on the GeneTitan™ MCInstrument.

2. At the end of the array warm up time, open the pouch and scan the array plate barcode into the Batch Registration file.

3. Before you denature the hybridization ready samples:

a. Prepare the reagents from Module 3 by inverting the bottles 2 to 3 times to mix.

b. Upload the Batch Registration File.

See Appendix B, Register samples in GeneChip™ Command Console™, of the Axiom™ 2.0 Assay 24-Array Format ManualWorkflow User Guide.

c. Set up the GeneTitan™ MC Instrument.

See GeneTitan™ MC Protocol for Axiom™ Array Plate Processing Quick Reference (Pub. No. MAN0017718).

See Chapter 5, Array Processing with the GeneTitan™ MC Instrument of the Axiom™ 2.0 Assay 24-Array Format ManualWorkflow User Guide (P/N 703335).

4. Place the Hyb-Ready Plate in the thermal cycler block, secure the lid, and start the Axiom 2.0 Denature protocol.



Prepare the hybridization tray and load into the GeneTitan™ MC Instrument

The following instructions assume familiarity with techniques and procedures that are associated with loading and operating theGeneTitan

™ MC Instrument. If needed, review procedures before starting.

CAUTION! Perform these steps under a fume hood.

1. After the Axiom 2.0 Denature protocol has completed, remove the Hyb-Ready Plate from the thermal cycler and place it into a96-well metal chamber that has been prewarmed in an oven at 48°C.

2. Move the metal chamber containing the denatured Hyb-Ready Plate to a fume hood.

3. Remove the seal from the Hyb-Ready Plate, then discard.

4. Remove the hybridization tray from packaging.

5. Label the hybridization tray.

IMPORTANT! It is critical that you write only on the proper location of the hybridization tray (on the edge in front of wells A1 andB1). Do not write on any other side, because the writing can interfere with sensors inside the GeneTitan™ MC Instrument and result inexperiment failure.

Figure 1 Label the GeneTitan™ hybridization tray.• Do not label trays on the long side of the tray.

• Notched corner of the hybridization tray should face the front.

• Label the hybridization tray in this area.

6. Place the hybridization tray under the fume hood.

7. Using a P200 8-channel pipette set at 105 µL, slowly transfer the denatured samples in columns 5, 7, and 9 from the Hyb-ReadyPlate into the corresponding wells of the hybridization tray. Dispense to the first stop to avoid creating bubbles.

• Change pipette tips after each transfer. Discard the tip even if it shows some remaining volume.

• Ensure that there are no air bubbles present in the hybridization tray. Puncture any air bubbles that you see using a clean pipettetip.

• There is no need to spread the sample on the bottom of the hybridization tray wells. Sample distribution across wells occurswhen the array plate is stacked together with the hybridization tray by the GeneTitan™ MC Instrument.


8. Load the array plate and hybridization tray into the GeneTitan™ MC Instrument.

The hybridization tray must be loaded on the right side. The array plate must be loaded on the left side on its protective blue base.The clear plastic cover on top of the array plate should not be loaded into the GeneTitan™ MC Instrument.

1 2

Figure 2 Array plate on protective blue base and the hybridization tray properly loaded into drawer 6.

1 Array plate on protective base. 2 Hybridization tray.

IMPORTANT! After the GeneTitan™ MC Instrument has stacked the array plate and hybridization tray, the instrument extends thedrawer. Manually check the stacking by gently pressing the 6 latching points to ensure that the 2 parts are clamped properly, andcheck underneath the arrays to ensure that there are no bubbles. If bubbles are found, gently tap the plate on top to eliminate thebubbles. Do not tip/tilt the array plate/hybridization tray sandwich as you are inspecting the bottom for bubbles.

9. Follow the prompts in the software..

Hybridization continues on the GeneTitan™ MC Instrument for 23.5–24 hours before you can load the ligation, staining, andstabilization reagent trays into the GeneTitan™ MC Instrument.

10. Near the end of the 23.5–24 hour hybridization in the GeneTitan™ MC Instrument and approximately 1.5 hours from completion(22 hours after the start of hybridization), proceed to “Stage 5—GeneTitan™ reagent preparation” on page 16.

Figure 3 Stain tray with cover.

1 Stain tray.

2 Notched corner.3 Label the stain tray here.

IMPORTANT! It is critical that you write only on the proper location of the proper edge of the stain tray, as shown in the figure. Do NOTwrite on any other side, because this can interfere with sensors inside of the GeneTitan

™ MC Instrument and result in experiment failure.

About aliquoting reagents to GeneTitan™ trays

IMPORTANT! Always aliquot reagents to the bottom of the reagent tray. Avoid touching the sides or the top of the wells with the pipettetips. Droplets close to or on the top of the well dividers can cause the cover to stick to the tray during GeneTitan™ MC Instrumentprocessing.

For all trays, pipet into trays on the benchtop. If the trays are not being used immediately, protect them from light by covering with foil orplacing in a cabinet.

IMPORTANT! Remember to deionize the stain trays and the covers before aliquoting master-mixes.

When aliquoting ligation, staining, and stabilization reagents to the trays, it is not necessary to spread the reagent to each corner ofthe well. The reagent spreads evenly when the array plate is inserted into the reagent tray during processing with the GeneTitan™ MCInstrument.


Aliquot reagents to stain trays

You will need to add the appropriate master mix into columns 5, 7, and 9 of the “S1”, “S2”, “Stbl”, and “Lig” trays labeled in the previousstep.

1. Pipet or pour the master mix into the 4- or 8-channel side of the reagent reservoir:

• Stain 1 Master Mix into the 8-channel side of the “S1” reagent reservoir.

• Stain 2 Master Mix into the 4-channel side of the “S2” reagent reservoir.

• Stabilization Master Mix into the 4-channel side of the “Stbl” reagent reservoir.

• Ligation Master Mix into the 4-channel side of the “Lig” reagent reservoir.

2. Add 105 µL per well of each master mix into the appropriate stain tray. Dispense to the first stop only to avoid creating bubbles.

3. If:

• Bubbles are present, puncture them with a pipette tip.

• Droplets of liquid splashed onto the well dividers, place a laboratory wipe on top of the tray to blot and remove.

4. Place covers on the trays. Orient cover correctly on the tray with the notched corners together.

5. Protect the trays from light if not immediately loading onto the GeneTitan™ MC Instrument.

Aliquot the Axiom™ Hold Buffer to the scan tray

The scan tray is shipped with 2 covers, a bottom protective base and a top cover.

Figure 4 Scan tray with top cover and black protective base.

1 Black protective base (remove before loading).

2 Scan tray.3 Top cover.

The top cover is removed to fill the tray during the target prep process, while the scan tray is left on the protective base during this part ofthe process.

Note: Module 5 (Part No. 902797) has 3 Axiom™ Hold Buffer bottles that should be used to prepare the scan tray for the second, third,

and fourth plate.

1. Pour all the contents of the Axiom™ Hold Buffer into both sides of the 25 mL divided reagent reservoir, placed on the bench top atroom temperature.

2. Remove the scan tray from its pouch.

3. Remove the scan tray cover, but leave the scan tray on its protective black base.

CAUTION! Do not remove the scan tray from its protective black base until loading onto the GeneTitan™ MC Instrument. Toavoid scratching, do not touch the bottom of the tray with pipette tips.

4. Deionize the barcoded scan tray cover (Part No. 202757) that came with the scan tray.


5. Use a 12-channel P200 pipette with new tips to aliquot 150 µL of Axiom™ Hold Buffer to each well of the 96-plate scan tray.Dispense to the first stop and avoid touching the bottom of the tray.

You do not need to change pipette tips between additions of the Axiom™ Hold Buffer.

IMPORTANT! The scan tray has an open-bottom design, so it is very important that all 96 wells of the scan tray receive 150 µL ofAxiom™ Hold Buffer.

6. If droplets of liquid splashed onto the well dividers, place a laboratory tissue on top of the tray to blot and remove.

7. Cover the tray by orienting the notched corner of the scan tray cover over the notched edge of the tray and the flat side of the coveragainst the scan tray, then leave on the bench top.

8. Continue to the array processing ligate, wash, stain, and scan section for instructions on loading the reagent trays and scan tray.

Store remaining reagentsGather all the reagents from Module 4‑1 and Module 4‑2, then tighten all caps. Mark reagent pouches, tubes, and bottles to track use.Store Module 4‑1 at –20°C and Module 4‑2 at 4°C.
