Azioni biochim/fisiol
Apolipoprotein A-1(Apo-A1), is a major protein component of high density lipoprotein (HDL)in plasma1. The protein promotes cholesterol efflux from tissues to the liver for excretion, and it is a cofactor for lecithin cholesterolacyltransferase (LCAT) which is responsible for the formation of most plasma cholesteryl esters2. Apo-A1 was shown to assist in the improvement of predicting cardiovascular events3. The gene that encodes to Apolipoprotein A-1 is APOA1. This gene is closely linked with two other apolipoprotein genes on chromosome 114. Defects in this gene are associated with HDL deficiencies, including Tangier disease5, and with systemic non-neuropathic amyloidosis6. The protein is made up of one major isoform (pI 5.6) and two minor isoforms (pI 5.53 and 5.46). Apo-A1 shows a high content of a-helix structure6. The amphipathic regions in the α-helix structure seem to be responsible for lipid binding capacity. In aqueous solution, Apo-A1 shows self-association with minor conformational change7. In addition, it has been shown that Apo-A1 is implicated in the anti-endotoxin function of HDL via interaction with lipopolysaccharide or endotoxin8.

General Description
SILuLite APOA1 is a recombinant human protein expressed in human 293 cells. It is a monomer of 286 amino acids (including N-terminal signal sequence and C-terminal polyhistidine and V5 tags), with a molecular weight of 32.1 kDa. SILuLite APOA1 is an analytical standard designed to be used as starting material for preparation of calibrators and controls in LC-MS applications.

Reduced plasma high-density lipoprotein (HDL) cholesterol levels have been recognized as a highly significant independent risk factor for atherosclerotic cardiovascular disease. HDL levels are also inversely related to plasma triglyceride levels and there is a dynamic interaction between HDL and
