Concentration: | 1 mg / ml, determined by the Lowry method |
Source: | From fresh human plasma that has tested negative for Hepatitis C, HIV-I and HIV-II antibodies as well as Hepatitis surface antigens. |
Purification: | After series ultracentrifugations, Very Low Density Lipoprotein (VLDL) is isolated from human plasma. Apo CIII is purified from delepidated VLDL, followed by gel-filtration and DEAE-Sepharcyl chromatography. Minor impurities of other apo-proteins are then removed by antibody-Sepharose™ affinity column. |
Purity: | ≥ 99% by SDS-PAGE |
Buffer: | In 10 mM Tris-HCl, 0.15 M NaC1, 0.5 mM EDTA, 0.02 % NaN3, pH 8.0 |

Importance
Apo CIII contains 79 amino acid residues. The m.w. is 8.7 kDa (Brewer et al., 1974).
It may inhibit the activation of lipoprotein lipase by apo CIII. Apo CIII is a constituent of both apoB- and apoAI-containing lipoproteins in the circulation. Apo CIII plays a pivotal role in regulating the plasma metabolism of VLDL, IDL, and LDL, primarily by inhibiting receptor-mediated uptake of these lipoproteins by the liver (Sehayek and Eisenberg 1991, Aalto-Setala et al., 1992, Zheng et al., 2007)
