Antibodies generated against specific proteins are useful tools for studying the physiology and cell biology of the protein of interest. Although antibodies have been successfully generated against lipoprotein lipase (LPL) and used to elucidate many aspects of its biology, there have been problems with the specificity, affinity and availability of these antibodies. To circumvent these problems, we have expressed a portion of human LPL as a bacterial fusion protein. The human LPL bacterial fusion protein was utilized to generate polyclonal antibodies in rabbits that recognize intact human, rat and bovine LPL. Using these antibodies, it was possible to demonstrate a direct correlation between LPL mass and LPL activity from different samples of human post-heparin plasma. In addition, these antibodies were used to develop an ELISA for the measurement of LPL in tissue or plasma. This is a useful means for obtaining polyclonal antibodies to LPL in sufficient quantity and without contaminating mammalian proteins.
