myT BRAF-Ultra, an ultrasensitive version of myT BRAF, provides 0.01% sensitivity down to single-copy detection of BRAF mutations. myT BRAF-Ultra can detect less than 10 copies of mutant BRAF V600E/K with low breakthrough amplification from a background of 10,000 wild-type genomic DNA copies. While myT BRAF-Ultra works well with fresh frozen and FFPE samples, it is also good for use when the sample material is limiting or where the target is present at very low concentration, such as with circulating tumor cells, serum, plasma, and needle biopsies. Each myT BRAF-Ultra package includes sufficient reagents to assess up to 14 samples when run in triplicate, plus a positive and a negative control.
