– Alkaline phosphatase can be considered “our favorite enzyme” for reasons apparent to those who diagnose and treat metabolic bone diseases or who study skeletal biology. Few might know, however, that alkaline phosphatase likely represents the most frequently assayed enzyme in all of medicine. Elevated activity in the circulation is universally recognized as a marker for skeletal or hepatobiliary disease. Alkaline Phosphatase (Germ type) /ALPG Protein, Human, Recombinant (mFc) is expressed in HEK293 mammalian cells with C-mFc tag. The predicted molecular weight is 78.24 kDa and the accession number is P10696.
