Materials Sold Separately

• rCutSmart™ Buffer

1. XmaI is an isoschizomer of SmaI. XmaI produces a 5´ extension whereas SmaI produces blunt-ended fragments.
2. Impaired by CpG methylation.
3. star activity may result from a glycerol concentration of >5%.

1. Is XmaI activity sensitive to dam, dcm or mammalian CpG methylation?
2. How many base pairs should be added at the end of a PCR primer after the XmaI recognition site to guarantee that XmaI will cut properly?
3. Does XmaI have any isoschizomers/neoschizomers?
4. Does XmaI exhibit star activity?
5. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
6. 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?
7. Which NEB restriction enzymes are supplied with Gel Loading Dye, Purple (6X)?
8. Can you tell me more about the switch from BSA to Recombinant Albumin (rAlbumin) in NEBuffers?
