HotStart DNA Polymerase

HotStart DNA polymerase inhibits PCR by using pyrophosphate (PPi) to trap Mg²⁺ ions essential for PCR, then breaking the PPi down by using heat resistant enzyme pyrophosphatase (PPase) as the temperature increases while processing the PCR reaction

Product Overview

▶ Principles of HotStart DNA Polymerase

HotStart DNA Polymerase is a new concept of DNA polymerase that utilizes chemical interactions between pyrophosphate (PPi) and pyrophosphatase (PPase).
While divalent cation magnesium (Mg²⁺) plays an important role in PCR, the pyrophosphate binds with Mg²⁺ to form a complex that inhibits the PCR.
However, the Mg-PPi complex will decompose into Mg²⁺ and 2Pi by the thermostable pyrophosphatase (PPase) during the PCR reaction, allowing increased reactivity with the by-product of the digested PPi, 2Pi.

Features and Benefits
