FAQ: Can T4 DNA Polymerase be used in other NEBuffers and rCutSmart Buffer?

For fill-in reactions only: T4 DNA Polymerase can be used in NEBuffers r1.1, r2.1, r3.1 and rCutSmart Buffer as well as NEBuffers 1-4 and T4 DNA Ligase Reaction Buffer.

For blunting reactions requiring removal of overhangs: T4 DNA Polymerase can be used in NEBuffers r1.1, r2.1, and rCutSmart Buffer as well as NEBuffers 1, 2, and 4 and T4 DNA Ligase Reaction Buffer. NEBuffers r3.1 and 3 are not recommended when overhang removal is required.

Supplementation of dNTPs is required for all blunting reactions. Optimal activity is observed in NEBuffer r2.1. Recombinant Albumin (rHSA) supplementation is recommended when using a buffer that does not contain BSA or rHSA.
