Alkaline Phosphatase/ALPG Protein, Human (HEK293, His)

Alkaline Phosphatase/ALPG protein is an enzyme that hydrolyzes phosphomonoesters under alkaline conditions to release inorganic phosphate. Alkaline Phosphatase is involved in processes such as bone mineralization and intestinal phosphate absorption, and exhibits anti-inflammatory activity. Alkaline Phosphatase/ALPG protein, Human (HEK293, His), is a recombinant Alkaline Phosphatase/ALPG protein expressed in HEK293 cells and tagged with a C-terminal His tag^[1].

Alkaline Phosphatase/ALPG protein is an enzyme that possesses the capability to hydrolyze a range of phosphate compounds. It exhibits the ability to break down various phosphate molecules through its enzymatic activity. Alkaline Phosphatase acts as an alkaline phosphatase, catalyzing the hydrolysis of phosphate esters in an alkaline environment. Its enzymatic activity allows it to cleave phosphate groups from molecules such as nucleotides, proteins, and phospholipids, rendering them inactive. This versatile enzyme plays a vital role in various physiological processes, including bone mineralization, cellular signaling, and metabolism^[1].

Alkaline Phosphatase is constitutively expressed in epithelial cell lines such as human renal cells and Henle intestinal cells, but shows no basal expression in cells like HeLa Henle and HeLa NIH^[2].

Alkaline Phosphatase (Human; 200 µg; subcutaneous injection; 2-4 times) significantly reduces synovial macrophage infiltration and exhibits systemic anti-inflammatory effects in a rat arthritis model, with synergistic effects when combined with Methotrexate (HY-14519)^[3].
