1. BsaJI is an isoschizomer of SecI.

1. Do degenerate recognition sites need to be palindromic?
2. My restriction enzyme used to be available at a lower concentration. Why does it now come at a higher concentration of 10,000 u/ml?
3. What effect does BSA have on the performance of NEB’s restriction enzymes when included in the new buffers?
4. How can I access the old NEBuffer Activity Chart?
5. My restriction enzyme used to work well in the old NEBuffer but the new Performance chart indicates it has lower activity even though the only difference is the addition of BSA and removal of DTT to the new buffers. Why?
6. Why is my Restriction Enzyme not cutting DNA?
7. Why do I see a DNA smear on an agarose gel after a restriction digest?
8. Why do I see additional DNA bands on my gel after a restriction digest?
9. How many nucleotides do I have to add adjacent to the RE recognition site in order to get efficient cutting?
