Enzyme volume should not exceed 10 % of total reaction volume, due to glycerol content.

Enzymes
Enzyme | Recognition site | Supplied buffer(s) | Time saver? | Heat inactivation |
---|---|---|---|---|
AgeI | ACCGGT | Example | ||
PciI | ACATGT | Example | ||
EcoRI | Example | |||
BsrGI | T^GTACvA | NEBuffer 2, BSA | Yes | |
SacII | CCGCGG | Nebuffer 4 | No | |
NdeI | CATATG | |||
BamHI | GGATCC |
Double digests
NEB Double Digest finder: https://www.neb.com/tools-and-resources/interactive-tools/double-digest-finder
Double Digest tool: http://www.thermoscientificbio.com/webtools/doubledigest/
Enzyme combination | Buffer recommendation | Experience | |
---|---|---|---|
AgeI+PciI | NEBuffer 4 | Have used NEBuffer 1. Seems to work reasonably well, but may lead to lower CIP activity if dephosphorylating. | |
BsrGI+BamHI-HF | NEBuffer 4 | ||
XhoI + EcoRI | NEBuffer 2-4 | ||
XhoI + BamH | NEBuffer 3 | ||
XhoI + PciI | NEBuffer 3 |
