MultiCode® products from Luminex offer a flexible platform for both real-time and multiplex PCR-based assays. MultiCode® products are based upon the unique patented MultiCode® base pair, isoC and isoG. These synthetic DNA base pair differ from the naturally occurring base-pair in their hydrogen bonding pattern. As a result, the MultiCode® bases, isoC and isoG can only hydrogen bond with each other. This property enables site-specific incorporation of the isobases during amplification.
