Mouse/Rat Apolipoprotein H/ApoH Antibody Summary
Accession # Q01339
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Rat and Mouse Apolipoprotein H/ApoH by Western Blot. Western blot shows lysates of rat liver tissue and mouse serum. PVDF membrane was probed with 0.25 µg/mL of Sheep Anti-Mouse/Rat Apolipoprotein H/ApoH Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6575) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Apolipoprotein H/ApoH at approximately 50-60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Apolipoprotein H/ApoH
Apolipoprotein H (ApoH), also known as beta 2‑Glycoprotein I/ beta 2-GPI, is a variably glycosylated member of the complement control superfamily of proteins with a molecular weight of aproximately 50 kDa (1, 2). Mature mouse ApoH consists of four tandem Sushi/SCR repeats followed by one Sushi-like repeat (3, 4). Mature mouse ApoH shares 76% and 42% aa sequence identity with human and rat ApoH, respectively. Hepatocyte-derived ApoH binds directly to negatively charged phospholipids (5). It circulates as a component of lipoprotein particles and as a lipid-free serum protein (6). ApoH also associates with liposomes and apoptotic cell debris, thereby enabling their renal clearance via Megalin uptake (7, 8). Circulating levels of ApoH are postively correlated with triglyceride-rich lipoprotein (VLDL) components in type II diabetes (9). ApoH inhibits thrombosis by blocking the activation of Coagulation Factor XI but also shows procoagulant activity by inhibiting the activation of Protein C (10, 11). ApoH can be cleaved by Plasmin at Lys317‑Thr318, an action that is enhanced by heparin (12, 13). ApoH cleavage reduces its ability to bind phospholipids and inhibit Factor XI activation but confers the ability to bind Plasminogen (10, 12, 14). Cleaved ApoH also demonstrates antiangiogenic activity, whereas intact ApoH does not (14). The production of antibodies against ApoH is a hallmark of Antiphospholipid Syndrome (APS), an autoimmune disorder that leads to hypercoagulability and recurrent miscarriages (15). ApoH binds to the surface antigen of Hepatitis B Virus and is associated with the development of HBV-induced hepatocellular carcinoma (6, 16).
