HiScript II One Step RT-PCR Kit (Dye Plus) is specially designed for end-point PCR detection using RNA as a template (such as RNA virus). PCR products can be directly loaded for electrophoresis, which greatly saves time and labor. Using gene-specific primers (GSP), reverse transcription and PCR reactions are completed in one tube, no additional tube opening/pipetting operations are required, which improves detection throughput and reduces the risk of contamination. Integrating the superior performance of HiScript  II Reverse Transcriptase and Champagne TaqTM plus DNA Polymerase, with an optimized buffer system, the detection sensitivity of HiScript  II One Step RT-PCR Kit (Dye Plus) can reach 1 pg total RNA and can be amplified Fragments up to 10 kb. The kit is provided in a convenient Master Mix format. 2 × One Step Mix (Dye Plus) contains optimized buffer system, dNTP and loading dye; One Step Enzyme Mix contains optimized ratio of HiScript  II Reverse Transcriptase, RNase inhibitor and Champagne TaqTM plus DNA Polymerase.
