BbsI-HF has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10119525. Learn more.

We are excited to announce that all reaction buffers are now BSA-free. NEB began switching our BSA-containing reaction buffers in April 2021 to buffers containing Recombinant Albumin (rAlbumin) for restriction enzymes and some DNA modifying enzymes. Find more details at www.neb.com/BSA-free.

NEB high fidelity restriction endonuclease that recognizes the sequence GAAGAC(N)2^
Isoschizomers | Single Letter Code

Product Introduction

High-Fidelity (HF®) restriction enzymes have the same specificity as native enzymes, but have been engineered for significantly reduced star activity and performance in a single buffer (rCutSmart™ Buffer).  All HF-restriction enzymes come with Gel Loading Dye, Purple (6X).  Enjoy the enhanced performance and added value of our engineered enzymes at the same price as the native enzyme:
