Application
Alkaline phosphatase is used for conjugation to antibodies and other proteins for ELISA, Western blotting, and histochemical detection. It is routinely used to dephosphorylate proteins, such as casein, and nucleic acids. It may be used for protein labeling when high sensitivity is required. 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.. Product P4653 is from bovine kidney and is provided as a lyophilized powder containing Tris-citrate buffer salts.
Biochem/physiol Actions
Alkaline phosphatase dephosphorylates proteins and nucleic acids.
Physical form
Lyophilized powder containing Tris-citrate buffer salts
Analysis Note
由缩二脲测定的蛋白质
Assays in Tris buffer, pH 10.2 give activity approx. 2X that in the glycine buffer system. Assays in diethanolamine buffer, pH 9.8 give activity approx. 5X that of the glycine buffer system.
Other Notes
One unit will hydrolyze 1 μmole of 4-nitrophenyl phosphate per minute at pH 9.8 at 37 °C. Previously sold in "glycine" units.

We have reported previously that the 69-kDa major phosphoprotein, secreted by normal rat kidney (NRK) cells, is osteopontin, a glycosylated bone matrix protein. Here we show that this 69-kDa osteopontin is secreted by NRK cells in both phosphorylated (pp69) and
