Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μM filtered concentrated solution in PBS, pH7.4.
Endotoxin
Less than 0.1EU/μg of rHuApoA-I as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
Apolipoprotein A-I encoded by the APOA1 gene is the major protein component of high density lipoprotein (HDL) in plasma. It has a specific role in lipid metabolism. Apolipoprotein A-I 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). Apolipoprotein A-I is also isolated as a prostacyclin (PGI2) stabilizing factor and thus may have an anticlotting effect. Apolipoprotein A-I has been shown to interact with ABCA1, GPLD1 and PLTP. Apolipoprotein A-I binds to lipopolysaccharide or endotoxin and has a major role in the anti-endotoxin function of HDL. Mature human ApoA-1 shares 65% and 62%a.a. sequence identity with murine and rat ApoA-1, respectively. It has an approximate molecular weight of 28.1kDa.
