Application

Alkaline phosphatase is used for conjugation to antibodies and other proteins for ELISA, Western blotting, and histochemical detection. It may be used for protein labeling when high sensitivity is required. Product P4252 is an ammonium sulfate suspension in glycine buffer.
Alkaline phosphatase is used for conjugation to antibodies and other proteins for ELISA, Western blotting, and histochemical detection. It may be used for protein labeling when high sensitivity is required. Product P4252 has been used for bulk digestion of tRNA . Product P4252 is provided in the ratio of 30-90 units/mg of protein.

Analysis Note

The activity at pH 8.0 at 25 °C is approximately the same as at pH 10.4 at 37 °C.

Biochem/physiol Actions

Alkaline phosphatase, from Escherichia coli, is a dimeric, non-glycosylated protein which mainly reside in the periplasmic space. Three known isoforms exist. The enzyme requires zinc, and is activated by magnesium. E. coli akaline phosphatase has a broad specificity for phosphate esters.

Disclaimer

Presence of 0.1% SDS in the alkaline phosphatase assays will inhibit any nuclease contamination in the sample.

Other Notes

One unit will hydrolyze 1.0 μmole of p-nitrophenyl phosphate per min at pH 10.4 at 37 °C.
