DataSheet   

This ELISA kit is for quantification of ApoAI in pig. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for ApoAI has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any ApoAI present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for ApoAI is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of ApoAI bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Alternative names for ApoAI: Apolipoprotein A-I, ApoA1,

Background: 

Apolipoprotein A-I is the major protein component of high-density lipoprotein (HDL) in plasma. 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 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 (2). Defects in the gene encoding it are associated with HDL deficiencies, including Tangier disease, and with systemic non-neuropathic amyloidosis (3). A G/A polymorphism in the promoter of the ApoA-I gene has been associated with the age at which patients presented with Alzheimer disease (4). Protection from Alzheimer disease by ApoA1 may rely on a synergistic interaction with alpha-tocopherol (5). Amyloid deposited in the knee following surgery consists largely of ApoA-I secreted from chondrocytes (cartilage cells) (6). A wide variety of amyloidosis symptoms are associated with rare ApoA-I mutants. ApoA-I binds to lipopolysaccharide or endotoxin, and has a major role in the anti-endotoxin function of HDL.
