Lipoproteins, High Density (HDL) Antigen

The high density lipoprotein antigen from Antibodies.com is supplied as a 10 mg liquid preparation used in cardiovascular and metabolic disease research. HDL particles transport cholesterol from peripheral tissues to the liver via reverse cholesterol transport and contain apolipoprotein A-I and A-II as their main protein constituents. Researchers use this antigen as an immunogen for antibody generation, as a coating reagent for plate-based binding studies, and as a calibrator in immunoassays that quantify HDL or its associated apolipoproteins.

The liquid form dissolves readily into standard buffers, eliminating the need to reconstitute a lyophilized pellet and reducing handling steps before an experiment. Store the preparation refrigerated, and for longer-term studies freeze aliquots at -20 degrees C to preserve native particle structure. Applications include work on cholesterol efflux pathways, scavenger receptor interactions, and the anti-inflammatory properties attributed to HDL in published cardiovascular studies. The material is compatible with western blot, immunohistochemistry, and immunoassay workflows that require intact HDL particles or apolipoprotein detection. Each preparation is supplied at research use only grade for laboratory investigation of lipid metabolism and atherosclerosis-related mechanisms.
