  • General notes

    This antibody has been used to determine that atherosclerotic lesions in the human aorta contain considerable amounts of lipoproteins. These lipoproteins were observed to be complexed with components of the extracellular matrix (especially LDL and proteoglycans). The role of these matrix-lipoprotein complexes is not entirely clear, however, animal models of atherosclerosis have shown that increased cellular proliferation and increased production of extracellular matrix components occur following injury to the intimal layer of the aorta.

    At least 9 distinct polymorphic forms of apolipoproteins are known. The apolipoproteins act as stabilizers of the intact lipoprotein particles. Quantitative measurements of HDL, LDL and VLDL particles in human serum are often used to estimate an individuals' relative risk of coronary heart disease. In addition, quantitative immunological measurements of certain apolipoproteins (especially A-1 and B) have been suggested to be more accurate estimators of coronary heart disease than measurements of lipoprotein particles (especially HDL and LDL). Abcam's apo-lipoproteins are derived from human plasma by density gradient ultracentrifugation and HPLC.

  • FunctionApolipoprotein B is a major protein constituent of chylomicrons (apo B-48), LDL (apo B-100) and VLDL (apo B-100). Apo B-100 functions as a recognition signal for the cellular binding and internalization of LDL particles by the apoB/E receptor.
  • Involvement in diseaseHypobetalipoproteinemia, familial, 1
    Familial ligand-defective apolipoprotein B-100
    Defects in APOB associated with defects in other genes (polygenic) can contribute to hypocholesterolemia.
  • Sequence similaritiesContains 1 vitellogenin domain.
  • Post-translational
    Palmitoylated; structural requirement for proper assembly of the hydrophobic core of the lipoprotein particle.
  • Cellular localizationCytoplasm. Secreted.

Anti-Apolipoprotein B antibody images

  • ab7616 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal donkey serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab7616 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 donkey anti- goat IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for your enquiry. This is a polyclonal antibody and will therefore consist of a mixed population of IgGs each of which will recognise a different epitope. I am not sure that the antibody can be used to prevent the Apo B100 antibody from...

Thank you for your enquiry. When ab7616 was tested for application in Western blotting, it was tested against purified Apo B protein, which would be recommended as a positive control. If you have any additional questions, please contact us again.

Thank you for your email. Ab7616 was made against the whole apo B and should be able to recognize all the residues. I'm not familiar with the antibody from Polymedco, so unfortunately can't state how this antibody works in comparison. If you have any m...
