Designed to streamline experimental workflows, Megaplex™ RT Primers provide a single reaction solution when preparing cDNA for real-time PCR analysis on a TaqMan® MicroRNA Array. Human Pool A v2.1 contains RT primers for 377 unique microRNAs and 4 controls. The microRNA targets represented in this pool tend be better characterized, more broadly expressed and⁄or expressed at a higher level compared to Human Pool B. Human Pool A v2.1 is intended for use with the TaqMan® Array, Human MicroRNA A Card v2.0, however, it can also be used to prepare cDNA for real-time analysis using the individual TaqMan® MicroRNA Assays.
