The RainDrop™ digital PCR system alters the performance of molecular assays by enabling digital answers across a number of applications including low-frequency tumor allele detection, gene expression, copy number variation, and SNP measurement. Built on RainStorm™ picodroplet technology, the RainDrop system can generate up to 10 million picoliter-sized droplets per lane. It also features a two-color and varying probe intensity method that is capable of multiplexing up to 10 markers.
