Hotstart Taq DNA Polymerase

An Antibody-based HotStart Taq DNA Polymerase for increased specificity and robust sensitivity

HotStart Taq DNA Polymerase is designed to increase specificity and sensitivity in PCR. The HotStart Taq DNA polymerase is inhibited at temperatures lower than 70°C, but is fully activated after the first denaturation step. This prevents the formation of mis-primed products and primer-dimers during the reaction setup process, resulting in improved PCR specificity.

Features and Benefits

• Maximized specificity: Virtually eliminates non-specific amplification. Ideal for multiplex PCR with 2-6 amplicons.

• Improved sensitivity: Ecellent for PCR using low copy number targets

• TA cloning compatible: PCR products amplified with Hotstart Taq DNA polymerase have 3' A overhang and can be used for TA cloning.

• Versatility: HotStart Taq DNA Polymerase is ideal for a wide range of PCR applications.
