Prism Green 4X Mastermix uses a proprietary intercalating dye for specific amplification with an excellent signal-to-noise ratio and rapid extension rates. Low-copy-number targets can be detected with high efficiency over several logs of template concentration, while primer-dimer formation is efficiently minimized. Prism Green 4X qPCR Mastermix shows accurate and robust performance in a wide range of applications, including gene expression and copy number variation analysis.
