PCR amplification of nucleic acids is a fundamental technique used in many molecular biology laboratories. Despite its wide use, certain GC-rich regions of DNA, such as mycobacterial disease targets, still remain a challenge for amplification. Sequences high in GC content are associated with the formation of secondary structure, which prevents adequate strand separation and DNA polymerase amplification. As a consequence, mispriming is prominent, complicating specific product formation.
Despite the developments in conventional PCR, the complexity of multiplex Real Time PCR is still limited due to the lack of sufficient detection channels. To achieve high-end multiplexing capacity on standard Real Time PCR machines, Anapa Biotech has developed the MeltPlex® technology (see box on right).READ MORE
