Human APOH produced in Human Plasma having a molecular mass of 50kDa and pI of 5.6-6.4. It’s a major phospholipid binding protein and an important component to measure in the assessment of anti-phospholipid syndrome. APOH is also more specific than anti-cardiolipin antibodies and its presence correlates better with thrombotic risk.
Apoliprotein H (APOH) attaches to numerous kinds of negatively charged substances for instance heparin, phospholipids, and dextran sulfate. APOH prevents activation of the intrinsic blood coagulation cascade by attaching to phospholipids on the surface of damaged cells. APOH expressed by the liver and secreted in the plasma.
