PANScript DNA Polymerase


PANScript is widely used by molecular biologists that have come to depend upon the robust performance of this reagent. PANScript is a highly purified thermostable DNA polymerase offering very high yield over a wide range of PCR templates, and is the ideal choice for most assays. PANScript is a robust preparation and consistently delivers high yields with minimal background. PANScript possesses 5‘ to 3‘ exonuclease activity and leaves an “A” overhang such that the PCR product is suitable for effective integration into TA cloning vectors.

PANScript is supplied with 10x NH4-based reaction buffer, which provides optimal conditions for most experiments. Additional MgCl2 is provided to allow reaction conditions to be adjusted to suit the template. The specificity and performance of PANScript can be further improved with the use of 2x PAN Mate Additive (Cat No. PAN737041), which is designed for GC- or ATrich DNA, dirty templates or sequences with a high level of secondary structure.PANScript DNA Polymerase is purified from Thermus aquaticus.
