Detection of Human Apolipoprotein B/ApoB by Western Blot. Western blot shows human plasma. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Apolipoprotein B/ApoB Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3556) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). 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 Goat Anti-Human Apolipoprotein B/ApoB Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3556) at 1.7 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 labeling was localized to the cytoplasm and plasma membrane of hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Apolipoprotein B/ApoB
ApoB is a component of LDL and VLDL particles and chylomicans. ApoB100, the full-length ApoB synthesized in the liver, is a 512 kDa secreted palmetoylated glycoprotein that contains 4536 amino acid residues. A truncated ApoB designated ApoB48, containing the N-terminal 48% of ApoB100, is also produced by the intestine as a result of post-transcriptional modification of the ApoB mRNA. Additionally, C-terminal truncated ApoB, varying in length from ApoB25 to ApoB89, exists as a result of mutations in the ApoB gene. Within the region used as the immunogen, the amino acid sequence of the human peptide is 80% and 82% identical to the mouse and canine sequence, respectively.
