- | Protocol 13: Vector Dephosphorylation
| |
- |
| |
- |
| |
- | Reagents:
| |
- | * Antarctic phosphatase
| |
- | * 10x Antarctic phosphatase buffer
| |
- |
| |
- |
| |
- | Procedure:
| |
- |
| |
- | * Add 1/10 volume of 10x antarctic phosphatase reaction buffer to 1-5ug of DNA cut with any restriction endonuclease in any buffer.
| |
- | * Add 1ul of Antarctic phosphatase and mix.
| |
- | * Incubate 5 minutes at 37<sup>o</sup>C.
| |
- | * Heat inactivate for 5 minutes at 65<sup>o</sup>C.
| |
- | * Proceed with ligation.
| |
- |
| |
- |
| |
- | Notes:
| |
- |
| |
- | * Vector dephosphorylation can be useful in cutting transformation background, but it is very harsh.
| |
- | * It chews off 5' phosphates, but it also keeps chewing on the DNA ends, reducing total transformation efficiency.
| |
- | * Try without dephosphorylation first, and minimize exposure to phosphatase if you must resort to using it.
