ScienCell’s GoldNStart TaqGreen qPCR Master Mix (GTQMM) is a SYBR® Green dye-based qPCR master mix with a “hot-start” property. GTQMM is ideal for use in real-time quantitative PCR and DNA melt curve analysis. Kit Components. The 2X master mix contains SYBR® Green, dNTPs, Taq DNA polymerase, and an inert gold-color loading indicator (ScienCell, catalog #GQ300G) in a single tube. The “hot-start” property achieved through ScienCell’s unique chemically modified Taq DNA polymerase provides maximal inhibition of primer dimer formation. The advanced buffer formulation provides superior specificity and efficiency with a wide linear dynamic range. The inert gold-color loading indicator allows for better visualization and tracking of sample loading in qPCR plates or tubes.
