Thermo Fisher Scientific Invitrogen Collibri DNA Library Prep Kits
Thermo Fisher Scientific has launched several Invitrogen Collibri DNA Library Prep kits for use with high-throughput Illumina sequencing systems. The kits contain a tracking dye to visualize the library prep process and to show that reagents have been properly mixed. According to Thermo Fisher, the dyes do not interfere with enzymatic reactions and do not affect the sequencing results. Four versions of the kit are available, for either physically sheared or enzymatically sheared DNA, and involve either PCR or no PCR. The firm noted that all kits contain adapters with unique dual indexes or combinatorial dual indexes that enable up to 24 or 96 samples to be pooled for sequencing.
23andMe MUTYH-Associated Polyposis Report
23andMe has launched a new genetic health risk report for MUTYH-Associated Polyposis (MAP), one of three main hereditary colorectal cancer syndromes. According to the firm, the report examines two genetic variants in the MUTYH gene, Y179C and G396D, associated with MAP. The firm will offer the report to new Health + Ancestry Service customers as well as existing 23andMe Health + Ancestry Service customers genotyped on its most recent platforms. 23andMe received US Food and Drug Administration Clearance for the report in January.
BillionToOne Unity Prenatal Screen
BillionToOne has commercially launched its Unity prenatal screening assay. According to the firm, the assay is powered by its molecular counting technology and is the only prenatal screen that tests cell-free fetal DNA for cystic fibrosis, spinal muscular atrophy, and sickle cell disease using only one tube of the mother's blood. BillionToOne said it will make the test available at select clinics through its early-access program, with plans for a broader commercial launch later this year.
