製品詳細
Product Details
Phi29 DNA Polymerase is a DNA polymerase cloned from the Bacillus subtilis phage Phi29, expressed and purified in Escherichia coli. This enzyme exhibits remarkable strand displacement activity and high processivity, enabling it to synthesize DNA fragments of up to 70 kb in length. It also demonstrates strong template binding capability and possesses robust 3′→5′ exonuclease proofreading activity.

Shipping and Storage
This product is supplied and shipped on dry ice.
This product is stable after storage at:
- The product MUST be stored at -20°C or lower upon receipt;
- -20°C for 3 months under sterile conditions.
- *The 10× Reaction Buffer provided in this kit contains DTT, a sulfhydryl reducing agent essential for maintaining enzyme activity. When employing the 10× Reaction Buffer exposed to prolonged storage or repeated freeze-thaw cycles, fresh 40 mM DTT should be supplemented to the Reaction Buffer to ensure maximal enzymatic activity, as oxidative degradation of DTT progressively compromises its reducing capacity.
