DescriptionAlkaline phosphatase catalyzes the removal of 5' phosphate groups from DNA, RNA and ribo- and deoxyribonucleoside triphosphates.
- removing 5` and 3` phosphoryl groups from nucleic acids;
- preparing templates for 5` end labeling;
- preventing fragments from self ligating;
- dephosphorylation of proteins
Unit definitionOne unit is the amount of enzyme that hydrolyzes 1 μmol of p-nitrophenylphosphate to p- nitrophenol in a total reaction volume of 1 ml in 1 min at 37°C.
