|Application ||WB, IHC, IF|
|Calculated MW||30778 Da|
|Other Names||Apolipoprotein A-I, Apo-AI, ApoA-I, Apolipoprotein A1, Proapolipoprotein A-I, ProapoA-I, Truncated apolipoprotein A-I, Apolipoprotein A-I(1-242), APOA1|
|Target/Specificity||A synthetic peptide corresponding to residues near the N-terminus of human Apo A1 was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Apolipoprotein-A1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT). As part of the SPAP complex, activates spermatozoa motility.|
|Tissue Location||Major protein of plasma HDL, also found in chylomicrons. Synthesized in the liver and small intestine. The oxidized form at Met-110 and Met-136 is increased in individuals with increased risk for coronary artery disease, such as in carrier of the eNOSa/b genotype and exposure to cigarette smoking It is also present in increased levels in aortic lesions relative to native ApoA-I and increased levels are seen with increasing severity of disease.|

Apolipoprotein A1 (apo A1) is the major polypeptide of the human plasma high density lipoprotein (HDL). The structure and function of the apo A1 gene are of interest because of the inverse correlation shown between HDL levels and coronary heart disease (1). The 267 amino acid precursor initially undergoes intracellular co-translational proteolytic cleavage into proapoA-I. ProapoA-I is secreted from the cell and was isolated from thoracic duct lymph in the apoA-I1 isoform position. Results indicate that apo A1 is present in human plasma, and undergoes post-translational proteolytic cleavage to mature plasma apoA-I (2). Cleavage of this protein with cyanogen bromide yields four fragments designated in the order of elution from Bio-Gel P-30 as CNBr I, II, III, and IV (3).
