Two forms of Apo B exist: Apo B-100 and Apo B-48. The first is found in VLDL and LDL and is produced by the liver. The second is found in chylomicrons and originates in the intestine.
Apo B is purified from LDL isolated by density gradient ultracentrifugation (1.03-1.05 g/mL density range) followed by size exclusion chromatography in 10 mM deoxycholate, 50 mM NaCl, 50 mM Na2CO3, pH 10 (Walsh & Atkinson 1983).
PROPERTIES:
Apo B, which has a Mr of 550 kD, is the major protein found in LDL and is responsible for the cellular uptake of LDL particles from the plasma (Goldstein & Brown 1982). The Apo B prepared by this procedure is aggregated. The aggregates are not retained by a 0.45 mm filter, but migrate only a short distance into a 5% SDS PAGE gel. In the isolation buffer, Apo B gives a stable solution that is slightly hazy. | | Description | Human APOB produced from Human plasma having a molecular mass of 550 kDa. | | Source | Human Plasma | | Background | ApoB is the main apolipoprotein of LDL, IDL, VLDL and chylomicrons particles that serves as the carrier of lipids (fat molecules), as well as cholesterol, in the water surrounding the cells within every tissue across the body. Though all the functional aspects of Apolipoprotein B within the LDL and other elements are considered to be rather uncertain, it serves as the key organizing protein of all other carriers of lipids. across LDL membranes, apolipoprotein B also serves as a ligand for LDL receptors in many cells across the body, meaning, it shows that lipid carriers that are set to cross into cells with Apolipoprotein B receptors, this is the way that lipids are transported within and into cells. |
