Product Class: Restriction Endonuclease

StuI
neb31 cloned at NEB recombinant time saver dil_A 37 No dcm

StuI has been reformulated with Recombinant Albumin (rAlbumin) beginning with Lot #10156749. 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.

FAQs & Troubleshooting

FAQs

  1. Is StuI affected by methylation?
  2. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
  3. I tested your restriction enzyme on the substrate DNA recommended by NEB, and it appears to be active, however it does not digest my DNA. What could be the reason?
  4. Which NEB restriction enzymes are supplied with Gel Loading Dye, Purple (6X)?
  5. Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
