Note: This chapter gives procedures for manually preparing Oncomine™ BRCA

Assay, Chef-Ready Kit to prepare libraries on the Ion Chef™ System, see the Ion

AmpliSeq™ Library Preparation on the Ion Chef™ System User Guide (Pub. No.

MAN0013432).

Procedural guidelines

Reagent preparation:

• Thaw components that contain enzymes—such as 5X Ion AmpliSeq™ HiFi Mix,

FuPa Reagent, and DNA Ligase—on ice, and keep on ice during procedure.

• Thaw kit components other than enzymes, including genomic DNA and primer

panels, at room temperature until no ice is present in the tubes. Vortex all

reagents for 5 seconds (EXCEPT for enzymes, which should be ick-mixed) and

pulse-centrifuge before use. A pulse-centrifugation is a 5-second centrifugation at

maximum speed.

• If there is visible precipitate in the Switch Solution or the tube cap after thawing,

vortex or pipet up and down at room temperature to dissolve.

• If using the Ion Library Equalizer™ Kit, minimize freeze-thawing of Equalizer™

Primers by aliquoting as needed for your experiments. Primers can be stored at

4°C for one year.

• Pipet viscous solutions slowly and ensure complete mixing by vigorous vortexing

or pipeing up and down 5 times.

Oncomine

™

BRCA Research Assay User Guide

Laboratory and PCR setup:

•Use good laboratory practices to minimize cross-contamination of products. If

possible, perform PCR setup in an area or room that is separate from template

preparation. Always change pipee tips between samples.

• Before starting and after use, wash the working surface with 10% bleach followed

by two water rinses.

• Use inner wells of PCR plate if possible, and skip wells or columns to prevent

cross-contamination between samples.

• Use a calibrated thermal cycler that is specied in “Required materials not

supplied“ on page 8.

• Ensure that the correct cycling protocol is being used before starting the thermal

cycler.

• Store one 96-well cold block at –30°C to –10°C and one 96-well cold block at 2°C

to 8°C before use.

• Use the heated lid (105°C) for all thermal cycling conditions.

Pipeing recommendations:

• Use aerosol-barrier pipee tips. Change pipee tips between samples.

• Pipet viscous solutions (enzymes, beads, Switch Solution) slowly and ensure

complete mixing in the MicroAmp™ 96-well plate.

• Avoid introducing air bubbles when pipeing by keeping the pipee tip at the

boom of the solution in the wells.

• Set pipee to the recommended volume for up and down mixing and insert tip

into solution with pipee plunger depressed to avoid introducing air bubbles.

• Visually check tips to ensure that volumes are equivalent if using a multi-channel

pipee.

• Touch tip to side of well and slowly dispense reagent on the side of the well to

form a droplet. This practice enables you both to pipet small volumes accurately

and to see that you added reagent to the well.

• Ensure that reagent is adequately dispensed from the pipee tip.

Guidelines for DNA isolation and quantication:

• For each target amplication reaction, use 3,000 copies (10 ng of genomic DNA in

≤6 µL) from peripheral blood, cell lines, or FFPE tissue. See “Required materials

not supplied“ on page 8 for kits that are recommended for isolating DNA.

• We recommend the TaqMan® RNase P Detection Reagents Kit (Cat. No. 4316831)

for quantifying ampliable human genomic DNA. The Qubit™ dsDNA HS Assay

Kit (Cat. No. Q32851 or Q32854) can also be used with the Qubit™ 2.0 or Qubit™

3.0 Fluorometer.

• We do not recommend methods such as densitometry (for example, NanoDrop™

Spectrophotometers), because these methods do not discriminate between DNA

and RNA and therefore are sensitive to small fragments of hydrolyzed RNA. Use

of densitometry can lead to overestimation of the concentration of sample DNA,

under-seeding of the target amplication reaction, low-quality libraries, and low

library yields.

IMPORTANT! Primer pools and 5X Ion AmpliSeq™ HiFi Mix are viscous. Pipet slowly

and mix thoroughly. We recommend PCR setup on ice or a cold block.

1. For each sample, add components to 2 adjacent wells of a 96-well plate using a

low volume pipeor, as described in the following table. See the plate layout

example following the table.

Note: If preparing multiple libraries, master mixes without DNA are

recommended. Add master mixes to the plate rst.

IMPORTANT! Ion AmpliSeq™ Sample ID Panel primer pairs are included in the

2. Carefully remove the plate seal, then add 45 µL (1.5X sample volume) of

AMPure™ XP Reagent to each library. Pipet up and down 5 times to mix the bead

suspension thoroughly with the DNA.

3. Incubate the mixture for 5 minutes at room temperature.

4. Place the plate in a DynaMag™-96 Side Magnet, then incubate for 2 minutes.

Carefully remove and discard the supernatant without disturbing the pellet.

5. Add 150 µL of freshly prepared 70% ethanol, move the plate side-to-side in the

two positions of the magnet to wash the beads, then remove and discard the

supernatant without disturbing the pellet.

6. Repeat step 5 for a second wash.

7. Ensure that all ethanol droplets are removed from the wells. Keeping the plate in

the magnet, air-dry the beads at room temperature for 5 minutes. Do not overdry.

IMPORTANT! Residual ethanol droplets inhibit library amplication. Ensure

that all ethanol droplets are removed from the wells. If residual ethanol is

present, place the plate back on the magnet for 2 minutes and use a pipee to

remove the ethanol.

Proceed immediately to one of the following:

•Option 1: Equalize the library.

• Option 2: Quantify the library by qPCR.

• Option 3: Quantify the amplied library with the Qubit™ 2.0 or 3.0 Fluorometer,

or with the Agilent™ 2100 Bioanalyzer™ instrument.

Purify the library

Option 1: Equalize the library

IMPORTANT! We recommend the Ion Library Equalizer™ Kit when unamplied

library concentration is consistently 100−500 pM after elution in 50 µL. If sample

quality or quantity is variable or unknown, we recommend using the qPCR method

(see “Option 2: Quantify the library by qPCR“ on page 22).

The Ion Library Equalizer™ Kit (Cat. No. 4482298) provides a method for normalizing

library concentration at ~100 pM without the need for special instrumentation for

quantication. First amplify the Oncomine™ BRCA Research Assay library, then

capture the library on Equalizer™ Beads. After elution of the equalized library,

proceed directly to combining libraries and/or template preparation.

Warm all the reagents in the Ion Library Equalizer™ Kit to room temperature. Vortex

and centrifuge all reagents before use.

1. Prepare library amplication mix according to the following table. Prepare a

master mix for multiple reactions.

Order of

addition Component Volume per

reaction

Volume for 8

reactions[1]

1 1X Library Amp Mix (black cap) 50 µL 450 µL

2 Equalizer™ Primers (pink cap) 2 µL 18 µL

—Total 52 µL 468 µL

[1] One additional reaction added as overage to compensate for pipetting error.

2. Remove the plate from the magnet (at step 7 of "Purify the library"), then add

52 µL of library amplication mix to each well containing air-dried beads.

3. Seal the plate with a new MicroAmp™ Adhesive Film, vortex thoroughly, then

centrifuge at 100 × g for 30 seconds to collect droplets.

4. Place the plate back on the magnet for 2 minutes, then carefully transfer ~50 µL

of supernatant from each well to a new plate without disturbing the pellet.

5. Seal the plate with the adhesive lm, place a MicroAmp™ Compression Pad on

the plate, load the plate in the thermal cycler, then run the following program:

Stage Temperature Time

Hold 98°C 2 minutes

Cycling (9 cycles) 98°C 15 seconds

64°C 1 minute

Hold 10°C Hold

(for up to 1 hour)

Note: During cycling, wash the Equalizer™ Beads for later use (see “Wash the

Equalizer™ Beads (if not previously performed)“ on page 20).

1. Bring the Equalizer™ Beads to room temperature, then mix thoroughly.

Note: Beads for multiple reactions can be prepared in bulk, and stored in

Equalizer™ Wash Buer at 4°C for up to 12 months until use. After 12 months, re-

wash beads with an equal volume of Equalizer™ Wash Buer.

2. For each reaction, pipet 3 µL of beads into a clean 1.5-mL tube, then add

6 µL/reaction of Equalizer™ Wash Buer.

For example, if you have 4 reactions, add 12 µL of beads and 24 µL of wash

buer.

3. Place the tube in a magnetic rack for 3 minutes or until the solution is clear.

4. Carefully remove the supernatant without disturbing the pellet, then discard.

5. Remove the tube from the magnet, add 6 µL per reaction of Equalizer™ Wash

Buer, then pipet up and down to resuspend.

1. Centrifuge the plate at 100 × g for 30 seconds in a plate centrifuge to collect

contents at the boom of the wells.

2. Carefully remove the seal from the plate, then add 10 µL of Equalizer™ Capture

to each library amplication reaction.

3. Seal the plate with a clear adhesive lm, vortex thoroughly, then centrifuge to

collect droplets. Alternatively, mix by pipeing at least half the total volume up

and down at least 5 times before sealing the plate.

4. Incubate at room temperature for 5 minutes.

1. Mix the washed Equalizer™ Beads by gentle vortexing or pipeing up and down.

2. Add 6 µL of washed beads to each plate well containing the captured library.

3. Set the pipee volume to 40 µL, then pipet the mixture up and down at least

5 times to mix thoroughly.

4. Incubate at room temperature for 5 minutes. Briey centrifuge the plate to collect

all the liquid to the boom of the plate wells.

5. Place the plate in the magnet, then incubate for 2 minutes or until the solution is

clear.

6. Carefully remove the supernatant without disturbing the pellet.

Note: Check for droplets on the sides of the plate wells. If droplets are observed,

seal the plate, then gently tap the plate on a hard, at surface, or briey

centrifuge to collect all the liquid to the boom of the plate wells.

Note: Save the supernatant for repeat analysis if needed.

7. Add 150 µL of Equalizer™ Wash Buer to each reaction.
