The OncoScan CNV Plus Assay is a whole-genome copy number microarray-based assay that enables the detection of relevant copy number variations (CNVs) such as copy number gain and loss, loss of heterozygosity (LOH), copy neutral loss of heterozygosity (cnLOH), ploidy, allele specific changes, break point determination, mosaicism, clonal heterogeneity, and chromothripsis, as well as a panel of driver somatic mutations. It provides the reagents for sample preparation from formalin-fixed paraffin-embedded (FFPE) tumor samples and microarray hybridization and staining. Designed to cover the entire genome as well as known cancer drivers, this assay is part of a comprehensive workflow for researchers to understand high copy number mutations and somatic mutation data from as little as 80 ng of DNA per sample.

Key features of the OncoScan CNV Assay include:
Whole-genome copy number analysis—detect structural variants such as deletions, duplications, LOH, cnLOH, break point determination, ploidy, mosaicism and unbalanced translocations that are not well characterized by short read sequencing or targeted sequencing
Somatic mutation panel—covering 64 mutations in 9 genes (BRAF, EGFR, IDH1 and 2, KRAS, NRAS, PIK3CA, PTEN, and TP53)
Comprehensive coverage—whole-genome analysis of genes with established significance and importance in cancer and tumor progression as well as those with emerging evidence, helping to 'future-proof' the technology investment and minimize revalidation burden
Complete flexibility—detect chromosomal arm aberrations, focal changes, LOH, and cnLOH in a single assay, helping reduce costs and processing times
Robust performance—obtain standardized results from lot to lot and operator to operator
Low sample input and fast results—get results in 72 hours from only 80 ng of FFPE-derived DNA
Rapid analysis—free software provides intuitive data visualizations for hundreds of samples in minutes
High-resolution copy number detection in priority cancer genes—accurate identification of very small (50–125 kb) to large (Mb) copy number variations

Coverage and performance
• 50–100 kb copy number resolution in ˜900 cancer genes
• 300 kb genome-wide copy number resolution outside of the cancer genes
• Genome-wide LOH detection including copy-neutral LOH detection
• High dynamic range of 10+ copies
• Demonstrated concordance with FISH-confirmed amplifications in key cancer genes including ERBB2 (Her2), EGFR, MDM2, MYC, and FGFR1
• Known driver somatic mutations

Analysis software
Data analysis is free of charge and easy using one of the three available softwares:
Chromosome Analysis Suite (ChAS), for copy number calls for a few samples
• Somatic Mutation Viewer 1.1, for somatic mutation calls for a few samples

For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)

How can I export OSCHP files in VCF format?

To convert OSCHP files to VCF format in Chromosome Analysis Suite (ChAS), follow these steps:

- Open Analysis Workflow for ChAS
- Go to the QC results tab in the Analysis Workflow Window. Run the CEL files for the OncoScan data
- Once complete, under Files, open the OSCHP file for your sample (this is created by ChAS when you analyze)



- Under Exports, select Export to VCF, select the output directory and the samples and select OK



By following these steps, you should be able to convert OSCHP files to VCF format using ChAS. The files will be found in the output directory you selected. These steps can be used for any CHP files to be exported in VCF format.

Can I view OncoScan CHP (OSCHP) files from both OncoScan CNV Assay (Cat. No. 902293) and OncoScan CNV Plus Assay (Cat. No. 902695) simultaneously, in Chromosome Analysis Suite (ChAS) Software?

Yes, OSCHP files from both OncoScan CNV Assay (Cat. No. 902293) and OncoScan CNV Plus Assay (Cat. No. 902695) can be opened and viewed simultaneously in Chromosome Analysis Suite (ChAS) Software.
Note: The OncoScan CNV Assay does not contain the somatic mutation probes that are in the OncoScan CNV Plus Assay.

What is the difference between the OncoScan CNV Plus Assay (Cat. No. 902293) and the OncoScan CNV Assay (Cat. No. 902695)?

The main difference between the two products is in the reagent kit. The OncoScan CNV Plus Assay contains both somatic mutation probes and copy number probes. The OncoScan CNV Assay contains only copy number probes.

- The OncoScan CNV Plus Reagent Kit contains the OncoScan CNV Plus Somatic Mutation Probe Mix 1.0 (Part No. 902247).
- The OncoScan CNV Reagent Kit does not contain the Somatic Mutation Probe Mix. Instead, it contains Buffer C (Part No. 902696).

The OncoScan CNV Plus Assay detects genome-wide copy number changes, loss of heterozygosity (LOH), and a panel of somatic mutations. The somatic mutation panel includes 74 mutations found in BRAF, KRAS, EGFR, IDH1, IDH2, PTEN, PIK3CA, NRAS, and TP53.

The OncoScan CNV Assay detects genome-wide copy number changes and loss of heterozygosity (LOH).

What is the format size and fill volume for Oncoscan CNV Plus Assay (Cat. No. 902293)?

Oncoscan CNV Plus Assay is 8 micron, 100 format. 160 µL Hyb mix is added to the array. There should be no air bubble after the hyb mix is added and the chamber should be filled completely.

Is there an equivalent metric for the "Offset Flag" in the QC and Sample Info tab in Chromosome Analysis Suite (ChAS) for OncoScan?

There is no available equivalent to the "Offset Flag" in the QC and Sample Info tab in ChAS. The "Offset Flag" is a QC metric that is found in the Analysis Dashboard for OncoScan products. This QC metric lets us know if the TuScan algorithm detected that the usual normalization method was off, and therefore required readjustment.
