- Phosphate group removal to reduce self-ligation and vector background.
- Dephosphorylation of DNA 5' termini DNA prior to kinase labeling reactions
E. coli strain C75
Bacterial Alkaline Phosphatase (E.coli
) is extremely stable and is not completely heat inactivated; therefore, reaction products need to be twice purified via phenol-chloroform extraction followed by ethanol precipitation.
Supplied with 10X Reaction Buffer [500 mM Tris-HCl (pH 9.0), 10 mM MgCl2]
