GC-rich PCR products
GC-rich templates, such as the 5' ends of many mammalian cDNAs, are difficult to amplify using conventional PCR techniques due the presence of secondary structures that resist denaturation and prevent efficient primer annealing. Takara Bio offers several DNA polymerases designed to handle such challenging targets, with amplification of templates that contain up to 90% GC content.
Featured product

How the leopard lost its spots
Why do the offspring of some leopards hide their spots, resulting in black panthers? An international team of researchers focused on ASIP, a gene that causes dark coat coloration in other felines. Takara Bio's LA Taq with GC Buffer was used to sequence a tricky stretch of exon 4 in leopards and Asian golden cats, identifying SNPs associated with melanistic coat color. Scientists can now answer the curious question of how leopards produce panthers. That's Good Science!
