2X Taq Mastermix – Red is a ready-to-use solution containing Taq DNA polymerase, dNTPs, MgCl₂, optimized reaction buffers, and a red tracking dye that allows direct loading of PCR products onto agarose gel without the need for additional loading dye. It enables efficient PCR amplification of DNA templates (0.2–2 kb) while simplifying workflow by reducing pipetting steps and minimizing contamination. The mix allows quick reaction setup and easy optimization by varying only template or primer concentrations. It is designed to deliver consistent and reproducible amplification across a wide range of templates.
