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.
