CancerSeq™ Paraffin Tissue Samples
Extensively validated tumor tissues
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 variations (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 mutations.

Real Tumor Tissue vs. Cancer Cell Lines
Real tumor tissues are far more representative of real clinical disease than genetically engineered tumor cell lines. 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; real 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.
