Bio-Rad Laboratories SARS-CoV-2 Controls

Bio-Rad Laboratories has launched the SARS-CoV-2 S gene alpha, beta, gamma, and epsilon variant controls as part of its Exact Diagnostics line of molecular quality control products for research testing. The controls are intended to be validated as independent external run controls and used for research testing with molecular assays targeting mutations in the SARS-CoV-2 Spike (S) gene. They are intended to be used with assays detecting SARS-CoV-2 variant RNA and to be processed in the same manner as patient specimens to monitor all the steps of molecular assays, Bio-Rad said. The variant S genes and human gDNA are internally targeted to 200,000 copies/ml and 75,000 copies/ml, respectively, using Bio-Rad Droplet Digital PCR to ensure lot-to-lot consistency, the company added.
