Amsbio Circulating Tumor DNA Reference Standards

Amsbio has launched a new range of circulating tumor DNA reference standards: a set of highly characterized, quantitative multiplex quality controls to support the development of new assays. The standards are engineered to mimic the fragmentation profile of nucleosomal ctDNA (aproximately 166 bp) observed in real patient samples across a range of allele frequencies. Pre-validated by digital PCR, the kits include cancer-associated mutations in EGFR, PIK3CA, NRAS and KRAS, and are available as purified DNA or in a synthetica plasma.
