Product Class: Restriction Endonuclease

SalI
neb31 cloned at NEB recombinant time saver dil_A 37 65 Heat CpG

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 restriction endonuclease that recognizes the sequence G^TCGA_C
