Description

The qScript cDNA Synthesis Kit is a sensitive and easy-to-use solution for RNA quantification using two step RT-qPCR. The novel qScript Reaction Mix provides all the necessary components for cDNA synthesis except enzyme and RNA template. qScript reverse transcriptase is a mixture of an engineered MMLV RT and a ribonuclease inhibitor protein. This economical, highly stable stabilize, 2-component reagent system has been rigorously optimized to ensure sensitive and linear RNA detection with a wide-range of input RNA and relative abundance. Reagent performance is unaffected by repetitive freeze/thaw cycling (>20X), conferring greater ease-of-use and assay performance consistency. Oligo (dT) and random primers are pre-blended in a precise ratio to provide equal representation of 5′ and 3′-sequences for accurate gene expression quantification. The resulting cDNA product is directly compatible with all qPCR chemistries or conventional end-point RT-PCR of amplified fragments ≤1 kb in length.
