SeraCare Seraseq Solid Tumor Mutation Mix-I

SeraCare Life Sciences has launched the Seraseq Solid Tumor Mutation Mix-I (AFI-10) a reference material for next-generation sequencing-based tumor profiling assays. The kit contains the same mixture of mutations in key oncogenes and tumor suppressor genes as in the previously launched AF20 mix, but is offered at five additional allele frequencies, SeraCare said. By offering a set of material at 10, 8, 5, 3, and 1 percent allele frequency, this product enables laboratories to test their lower limit of variant frequency against a known and well-characterized reference material, the company added.
