Promega Maxwell RSC miRNA Plasma, Serum Kit

Promega has launched its Maxwell RSC miRNA Plasma and Serum kit. The firm said that the kit offers oncology and translational researchers a simple and automated protocol to purify circulating RNA — including miRNA — from plasma, serum, and enriched exosomes for techniques such as next-generation sequencing or droplet digital PCR. Researchers can use the kit with Promega's Maxwell RSC and RSC 48 instruments, which the firm said will reduce hands-on time for researchers and provide consistent, high-quality, and amplifiable miRNA.
