Infinium omni2 5exome 8 v1 3 or v1

Manufactured by Thermo Fisher Scientific

The Infinium Omni2.5Exome-8 v1.3 or v1.4 is a high-density genotyping array designed for comprehensive genetic analysis. It contains over 2.5 million markers, including exome-focused content, to provide a broad overview of genetic variation. The array is intended for use in large-scale genomic studies and can be processed in a 96-well plate format.

Each model underwent analysis using the Illumina Infinium Omni2.5Exome-8 v1.3 or v1.4 or the Affymetrix SNP 6.0 array. These samples were processed according to PDXnet specifications1 (link) using the tumor-only procedure outlined by recommendations in ASCAT62 (link). To account for median-centered differences between the Affymetrix and Illumina chip, we calculated platform-specific thresholds for amplifications and deletions (0.9 and −0.9 for Affymetrix CN ratios and 0.6 and −0.6 for Illumina CN ratios; Extended Data Fig. 5). The gene set chosen for Fig. 1a was curated from a set of four breast cancer or pan-cancer publications63 (link),64 (link) as well as sentinel genes, that is, genes that represent a larger genomic region, from public and commercial sources, including FoundationOne, cBioPortal and Ambry Genetics Corporation. These extra genes include FGF3, CDK12, NOTCH2, H3P6, SIPA1L3, ADCY9, FAM72C, SDK2, CDK18, STX4, TNFRSF10C, NKX3-1, LYN, JAK1, JAK2, CD274, PDCD1LG2, ERBB4, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, MRE11A, MUTYH, NBN, NP1, PALB2, RAD50, RAD51C and RAD51D.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
