Scientific Data

Western Blot Detection of Human Apolipoprotein H/ApoH antibody by Western Blot. View Larger

Detection of Human Apolipoprotein H/ApoH by Western Blot. Western blot shows lysates of human liver tissue. PVDF membrane was probed with 1 µg/mL Goat Anti-Human Apolipoprotein H/ApoH Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5087) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). For additional reference, recombinant human ApoH (5 ng) was included. A specific band for Apolipoprotein H/ ApoH was detected at approximately 50-60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Apolipoprotein H/ApoH in Mouse Pancreas. Apolipoprotein H/ApoH was detected in perfusion fixed frozen sections of adult mouse pancreas using Goat Anti-Human Apolipoprotein H/ApoH Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5087) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to pancreatic islets.

Background: Apolipoprotein H/ApoH

ApoH (Apolipoprotein H; also beta 2-Glycoprotein 1/ beta 2-GPI) is a 50 kDa, secreted, variably glycosylated, monomeric member of the complement control superfamily of molecules. It is produced by hepatocytes and is bound to HDL particles. Circulating ApoH blocks the intrinsic clotting pathway, and binds to exposed phospholipids on apoptotic cells. Mature human ApoH is 326 amino acids (aa) in length (aa 20‑345). It contains four Sushi repeats (aa 21‑260) and one C-terminal kringle domain (aa 261‑345) that binds heparin and phospholipids. At least two ApoH isoforms exist, one showing a 31 aa substitution for aa 140‑345, while a second represents a bioactive plasmin cleavage product that removes the C-terminal nine amino acids. Mature human ApoH shares 76% aa identity with mouse ApoH.
