Application
Alkaline phosphatase can be used to dephosphorylate casein and other proteins. Alkaline phosphatase may be also be used to dephosphorylate the 5′-termini of DNA or RNA to prevent self-ligation. DNA or RNA can also be tagged with radiolabeled phosphate (via T4 polynucleotide kinase) after dephosphorylation with alkaline phosphatase..
High specific activity grade recommended for antibody and protein conjugation.
Biochem/physiol Actions
The enzyme has a broad specificity for phosphate esters of alcohols, amines, pyrophosphate, and phenols. It is routinely used to dephosphorylate proteins and nucleic acids.
Physical properties
Bovine intestinal alkaline phosphatase is a dimeric, membrane-derived glycoprotein. At least three isoforms exist, which typically possess two N-linked and one or more O-linked glycans per monomer.

Unit Definition
One DEA unit will hydrolyze 1 μmole of 4-nitrophenyl phosphate per minute at pH 9.8 at 37 °C. (One glycine unit is equivalent to ~3 DEA units)
Physical form
Solution in 40% glycerol containing 6 mM Tris, 6 mM MgCl2 and 0.12 mM ZnCl2, pH approximately 7.6
Analysis Note
Package sizes are based on DEA units
