SeraCare Seraseq Breast CNV; Lung and Brain CNV Mix

SeraCare Life Sciences launched the Seraseq Breast CNV and Seraseq Lung and Brain CNV Mix, reference materials for analyzing copy number variation. Both have been built with biosynthetic technology that can be easily scalable to incorporate new CNVs over time, and were developed so that clinical labs conducting NGS-based tumor profiling for cancer can better understand and characterize their assays, SeraCare said. They were precisely quantified using highly sensitive digital PCR assays to analyze amplification of EGFR, MET, FGFR3, MYC, ERBB2, and MYCN genes at +3, +6, and +12 copies against a single well-characterized genomic background, the company said.
