QTaq DNA Polymerase for Real-Time qPCR

QTaq DNA Polymerase Mix contains a robust, full-length Taq DNA Polymerase designed to keep you at the forefront of quantitative PCR (qPCR) technology. The mix includes a built-in hot start antibody, which guarantees increased specificity in each PCR reaction. Optimized for use with most qPCR detection methods and applications, our polymerase mix provides high sensitivity and reproducibility for qPCR and qRT-PCR (quantitative reverse transcriptase PCR) assays. For convenience, the QTaq PCR Buffer includes dNTPs, Mg2+, and ROX passive reference dye.

Maximum Sensitivity

Taq polymerase is the premier choice for qPCR applications, whether real time or endpoint. It displays a robustness and sensitivity that ensure the optimal amplification of a variety of targets—including rare ones—from both cDNA and genomic templates, in both single and multiplex reaction formats. This is especially important when amplifying low-copy-number targets or complex templates.

Hot Start Antibody Delivers High Specificity

By blocking polymerase activity during the initial PCR reaction set-up, our hot start system prevents the formation of primer dimers and other artifacts of low-level synthesis that can arise prior to thermal cycling. Our antibody-mediated hot start system also allows for higher specificity compared to other traditional Taq-based systems. This is particularly important when multiplexing two or more targets in the same reaction, or when quantifying with homogeneous fluorescence detection systems, such as SYBR Green I, that bind to all double-stranded DNA products (including primer-dimers and non-specific amplicons).

Ready-to-use qPCR master mix that contains full-length Taq polymerase and SYBR Green I is also available.
