Human Apo-A1 Protein, His Tag

  • Synonym
    Apolipoprotein A-I,APOA1,MGC117399
  • Source
    Human Apo-A1, His Tag (AP1-H5225) is expressed from human 293 cells (HEK293). It contains AA Arg 19 - Gln 267 (Accession # NP_000030.1).
    Predicted N-terminus: Arg 19
  • Molecular Characterization
    Online(Arg 19 - Gln 267) NP_000030.1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 29.8 kDa. The protein migrates as 27 kDa under reducing (R) condition (SDS-PAGE).

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • Background
    ApoA1 is also known as apolipoprotein A-I, ApoA-I , and is the major protein component of high density lipoprotein (HDL) in plasma. It has a specific role in lipid metabolism. Chylomicrons secreted from the intestinal enterocyte also contain ApoA1 but it is quickly transferred to HDL in the bloodstream. The protein promotes cholesterol efflux from tissues to the liver for excretion. It is a cofactor for lecithin cholesterol acyltransferase (LCAT) which is responsible for the formation of most plasma cholesteryl esters. ApoA-I was also isolated as a prostacyclin (PGI2) stabilizing factor, and thus may have an anticlotting effect. Defects in the gene encoding it are associated with HDL deficiencies, including Tangier disease, and with systemic non-neuropathic amyloidosis. In addition, it has been shown that ApoA1 is implicated in the anti-endotoxin function of HDL via interaction with lipopolysaccharide or endotoxin.
