Buffers
NEBuffer EcoR I
Notes
- 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.
