Phosphatase, Alkaline from Escherichia coli, ammonium sulfate suspension, 30-90 units/mg protein (mo

Analysis Note

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

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.

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.
