BioChain’s CancerSeq formalin fixed paraffin embedded (FFPE) tissues are tumor tissues that have been prescreened extensively for single nucleotide polymorphisms (SNPs), insertions & deletions (indels), and copy number va...(Expand Details)riations (CNVs). Targeted Next Generation Sequencing (NGS), using cancer gene panels, was performed to identify mutations and mutational hotspots. These tissues are ideal for verification, genotyping, or identification of new mutational hotspots.

The advantage of using real tumor tissues versus genetically engineered tumor cell lines, is that the tissues are far more representative of real clinical disease. Cancer cell lines or genetically altered cell lines have been used widely for in vitro tumor models, but these possess only a small proportion of the genetic variances seen in tumor tissues. Actual tumors generally carry multiple mutations instead of just one or two. Numerous studies have pointed out the striking genetic differences between cell lines and tumor samples by comparing microarrays, copy number changes, mutations, and mRNA expression profiles 1-5.

Briefly, genomic DNA was extracted from the FFPE tissues and validated by targeted NGS with either Illumina’s TruSeq Amplicon - Cancer Panel (TSACP) or ArcherDX’s VariantPlex Solid Tumor Panel which include 48 or 67 cancer-related genes. Our pre-screened tissues come with detailed information regarding donor and cancer type, as well as NGS information such as chromosomal position, variant type (SNP or indel), alternate allele variations, quality score, depth of coverage, allele type, transcript ID and more. We offer the pre-screened tissue as mounted sections or curls. Please inquire for other options such, as whole block or extracted nucleic acids.
