The amaR OnePCR™ is a ready-to-use PCR reaction mixture. Simply add primers, template, and water, the reagent will execute primer extensions and other molecular biology applications. The amaR OnePCR™ is a pre-mixed solution containing Taq DNA polymerase, PCR buffer, dNTPs, gel loading dyes, and fluorescence dye. The amaR OnePCR™ which contains the Taq DNA polymerase, is purified from the E. coli., and expresses the Thermus aquaticus DNA polymerase gene. This enzyme has a 5′ → 3′ DNA polymerase and the 5′ → 3′ exonuclease activity but lacks the 3′ → 5′ exonuclease activity. The amaR OnePCR™, which contains the fluorescence dye, is directly detected on BLooK LED transilluminator or UV epi-illuminator after the DNA electrophoresis. The amaR OnePCR™ contents red tracking dyes, providing a safe, non-toxic and non-mutagenic alternative to ethidium bromide for instantaneous band visualization, that are environmentally friendly containing no hazardous chemicals.
