Descriptions

Analysis Note

Package sizes are based on DEA units

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 form

Solution in 50% glycerol containing 5 mM Tris, 5 mM MgCl₂ and 0.1 mM ZnCl₂, pH 7.0

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.2 The enzyme requires zinc, and magnesium or calcium divalent ions for activity.

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)
