Introduction

KaryoStat™ Assay is intended to be used with genomic DNA in conjunction with

CytoScan™ Optima array, GeneChip™ System 3000, and Chromosome Analysis Suite

(ChAS).

KaryoStat™ Assay is equivalent to and comprised of CytoScan™ Optima arrays and

reagents. CytoScan™ Optima array consists of features covering control, copy number

(CN), and single-nucleotide polymorphism (SNP) probes. There are a total of 18,018

CN markers and 148,450 SNP markers uniformly spaced over the genome with

enhanced interrogation of 396 regions of prenatal interest. Cumulatively, through the

collection of SNPs and non-polymorphic probes the application provides the ability to

support detection of CNVs, enable the elucidation of allelic imbalance (i.e., the paern

of inheritance deviates from expected Mendelian inheritance paerns), identify copy

number neutral abnormalities such as absence (AOH) or loss of heterozygosity

(LOH), and characterize unbalanced translocation events in the samples of interest.

Assay warnings and precautions

Follow universal precautions for laboratory and assay procedures, and waste

disposal. Follow federal, state, local, and within-country regulations.

Before you begin, go to Appendix A, “Workow and practices“for specic setup

instructions, and equipment and technique illustrations, and Appendix B, “Thermal

cycler programs“ for specic thermal cycler program set ups.

For additional specic warnings, precautions, and procedures, see:

Assay User Guide

Visit our website for all user guides (CytoScan™ Optima Assay User Guide, Chromosome

Analysis Suite (ChAS) User Guide, GeneChip™ Command Console™ User Guide, GeneChip™

Fluidics Station 450 User Guide for AGCC, GeneChip™ Hybridization Oven 645 User

Guide), and training materials (containing training kit and positive control DNA), SDS

for all hazards in CytoScan™ Optima Assay reagents.

The physical and toxicological properties of the products in this kit have not been

thoroughly investigated. Follow prudent laboratory practices and use general

laboratory safety equipment (eye protection, labcoat, and lab gloves) and good

personal hygiene when working with these or any laboratory reagents. Refer to the

Safety Data Sheet for more information.

Proper laboratory practice is necessary as previously amplied PCR product is the

most likely potential source of contamination. We strongly recommend two separate

work areas be used to minimize the risk of cross-contamination during the assay

procedure. It is essential to adhere to workow recommendations. PCR reactions

should be set up in the Pre-PCR Area only. Personnel should not reenter the Pre-PCR

Clean Area once exposed to PCR products without rst showering and changing into

clean clothes.

Carefully reading and following the protocol as wrien is essential. The KaryoStat™

Assay has been validated using the reagents and suppliers listed. Substitution of

reagents and not following detailed procedures are not recommended as your results

could be suboptimal.

• Follow standard procedures and single-direction workow for the Pre-PCR

laboratory area.

• Use dedicated equipment for each area (e.g., thermal cyclers, microfuges, pipees

and tips, ice buckets, etc.)

• Place all reagents and master stocks in use area. Do not move equipment between

Pre- and Post-PCR Rooms, e.g., ice buckets, pipees, etc.

• Use separate copy of assay procedure in Pre- and Post-PCR areas.

• Follow procedures for re-entry of Pre-PCR Clean Room from post-PCR.

• If pre-PCR work is done in a laminar ow hood or PCR cabinet, then additionally

ensure:

– laminar ow hood is always on

– UV lamp is on when not in use

• Use kit after its expiration date.

• Use reagents after more than four freeze-thaw cycles.

• Use any water other than Nuclease-free Water supplied with the CytoScan™

Optima Kit.

• Reuse a plate seal.

Precautions

Pre/post-PCR

Do not

Chapter 1 Product information

• Use 250 ng of double-stranded genomic DNA (gDNA) that is not degraded (size

>10 kb by gel analysis), not contaminated, and free of PCR inhibitors; verify

concentration using quantitation method specic to dsDNA. The purity ratio

(A260/A280 ratio) of input DNA must be between 1.7–2.1.

• Follow procedures for gowning, etc.

• Use nuclease-free pipee tips with aerosol barriers for all pipeing steps.

• Use extraction methods that yield DNA compatible with DNA quality as

specied above.

• Chill essential equipment such as cooling blocks and reagent coolers before use.

• Keep all tubes, master mixes, and working solutions in chilled cooling blocks on

ice.

• Keep enzymes at –25 to –15°C until needed, then immediately place in reagent

cooler chilled to –15 to –25°C. Do not store enzymes at –80°C.

• Where indicated, keep reagents chilled at 2 to 8°C and place on ice during use.

After thawing, immediately place on ice and use within 1.5 hours.

• Maintain sample consistency; ensure all transitions to incubation temperatures

are rapid and wellcontrolled. Enzyme activity is a function of temperature.

• Enzyme handling:

– Maintain tube in –15 to –25°C cooler

– Quick spin and vortex 1 to 3 seconds

– Place back in cooler for use

• Because Fragmentation Reagent activity can decline over time after dilution on

ice, add it to the samples as quickly as possible.

• Maintain 15 to 30°C (RT) throughout the procedure.

• Always use freshly prepared master mixes.

• Use only Nuclease-free Water supplied with the kit.

• Follow instructions for sealing, vortexing, and centrifuging. Ensure that plates are

tightly sealed to prevent sample loss and cross-well contamination. Always use a

new seal.

• Pipet accurately using calibrated pipeors.

• Use equipment calibrated according to manufacturer instructions.

• Use only specied assay stopping points.

• Check that your spectrophotometer or NanoDrop is accurately calibrated, and be

sure the OD measurement is within the linear range of the instrument as per the

manufacturer’s recommendations.

• Hybridization oven temperature is critical to the performance of the assay. Use

only the GeneChip™ Hybridization Oven 645. Hybridization ovens should be

serviced at least once a year to ensure that they are operating within specication.

Controls

• Use of a pre-qualied sample [e.g., Ref 103 (Cat. No. 900421)] as a positive control

is highly recommended. These controls are eective troubleshooting tools that

will help you conrm the successful completion of each stage of the assay.

• Use a negative control. Use a blank well with Low EDTA TE Buer (Cat. No.

902424). The absence of bands on your PCR gel for the negative control conrms

no previously amplied PCR product has contaminated your samples.

• Oligonucleotide controls are included in the reagent kit. These controls are added

to the target samples prior to hybridization.
