NEBuffer EcoR I
- Improving the efficiency of EcoRI/SpeI Double Digest.
- Reaction Volumes - I used to have very inconsistent results when digesting with EcoRI, using the 20μl reaction volume. Using the Knight Lab's 50μl mix has recently given good results. I haven't tested this enough to say it is a statistically significant result. --BC 13:39, 2 Jun 2005 (EDT)
- The custom EcoRI buffer provided by NEB contains Triton-X100. This detergent is very inhibitory in transformations, so direct ligation and cloning of DNA cut in this buffer is problematic. Remarkably small amounts of this buffer dramatically reduces transformation efficiency.
- The FastDigest restriction enzymes from Fermentas all work very efficiently in one universal buffer. I perform digests in a 30 μL reaction volume. *Karmella Haynes 14:07, 19 January 2012 (EST):
