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 [1]. The protein promotes cholesterol efflux from tissues to the liver for excretion. It is a cofactor for lecithin cholesterolacyltransferase (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.[2] Defects in the gene encoding it are associated with HDL deficiencies, including Tangier disease, and with systemic non-neuropathic amyloidosis.[3] In addition, it has been shown that ApoA1 is implicated in the anti-endotoxin function of HDL via interaction with lipopolysaccharide or endotoxin.

Recombinant Human Apo-A1 Protein (Human Apo-A1, His Tag) Arg 19 - Gln 267 (Accession # NP_000030.1) was produced in human 293 cells (HEK293).

Molecular Characterization
rhApoA1, a 250 amino acids protein with polyhistidine tag at C-terminus, and has a calculated MW of 29 kDa. The predicted N-terminus is Asp25. DTT-reduced protein migrates as 26-30 kDa protein.

Less than 1.0 EU per μg of the rhApoA1 by the LAL method.

>92% as determined by SDS-PAGE.
