Designed to streamline experimental workflows, Applied Biosystems® Megaplex™ RT Primers provide a single reaction solution when preparing cDNA for real-time PCR analysis on a TaqMan® MicroRNA Array. Rodent Pool B contains RT primers for 133 and 77 unique microRNAs for mouse and rat respectively plus 4 species specific controls. The microRNA targets represented in this pool tend be less well characterized, more narrowly expressed and⁄or expressed at a lower level when compared to Human Pool A. The pool can also be used to prepare cDNA for real-time analysis using the individual TaqMan® MicroRNA Assays.
