Scientific Data

Western Blot Detection of Human Apolipoprotein B/ApoB antibody by Western Blot. View Larger

Detection of Human Apolipoprotein B/ApoB by Western Blot. Western blot shows human plasma. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Apolipoprotein B/ApoB Monoclonal Antibody (Catalog # MAB4124) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Apolipoprotein B/ApoB at approximately 500 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Apolipoprotein B/ApoB in Human Liver. Apolipoprotein B/ApoB was detected in immersion fixed paraffin-embedded sections of human liver using Mouse Anti-Human Apolipoprotein B/ApoB Monoclonal Antibody (Catalog # MAB4124) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membranes in hepatocytes.

Background: Apolipoprotein B/ApoB

Human ApoB (Apolipoprotein B-100) is a 550 kDa, secreted, palmitoylated glycoprotein that is part of LDL and VLDL particles. It is made by liver and is 4536 amino acids (aa) in length. It binds LDL to the ApoB/E receptor. Multiple forms of ApoB-100 exist; ApoB-25, 26, 29, 37, 39, 48, and 74. The numbers reflect each molecule’s predicted MW as a percentage of ApoB-100 (512 kDa). Amino acids 1206-1414 of the precursor were used for immunization. Based on likelihood of secretion, this antibody may recognize B26 (1297 aa), B37 (1728 aa), B39 (1799 aa), and B48 (2152 aa). Over the immunization polypeptide range, human ApoB-100 is 80% and 82% aa identical to mouse and dog ApoB-100, respectively.
