Takara Taq DNA polymerase, hot start
The hot-start versions of TaKaRa Taq DNA Polymerase contain a mixture of Taq polymerase and a monoclonal antibody that binds to Taq polymerase, thereby preventing DNA synthesis at room temperature. During the initial DNA denaturation step (reaction temperature ~94°C), the antibody is denatured, releasing the polymerase and allowing DNA synthesis to proceed. The use of a hot-start PCR enzyme prevents nonspecific amplification due to mispriming and/or the formation of primer dimers during PCR assembly.
Several hot-start versions of Takara Taq are available:

Several hot-start versions of Takara Taq are available:
- TaKaRa Taq DNA Polymerase Hot Start Version—enzyme, buffer, and dNTPs are supplied as separate components
- Premix Taq DNA Polymerase Hot Start Version—2X premix containing Takara Taq HS enzyme, dNTPs, and an optimized reaction buffer
- TaKaRa Taq HS Perfect Mix—2X hot-start premix optimized for fast reactions. It contains a modified Taq DNA polymerase, which lacks exonuclease activities, and is compatible with a 20 sec/kb extension step
Overview
Integrated hot-start antibody for enhanced specificity: minimizes primer-dimer formation and reduces background, making it suitable for multiplex PCR. The hot start also allows for convenient reaction setup at room temperature.
