Monoclonal antibodies to low density lipoprotein used for the study of low- and very-low-density lipoproteins, in "ELISA" and immunoprecipitation technics.

Abstract:

:Seven monoclonal antibodies to low-density lipoprotein were studied by the ELISA for their reactivity with LDL or VLDL. Cotitration experiments showed that five of them are addressed to different antigenic epitopes. Two of the monoclonal antibodies were temperature independent whereas the others had a decreased binding activity at 37 degrees C compared to that obtained at 25 degrees C or 4 degrees C, suggesting the presence of antibodies directed to sequence or conformation epitopes, respectively. All antibodies reacted with both LDL and VLDL; four of them had a higher affinity for LDL and two others for VLDL. Immunoprecipitation of LDL and/or VLDL was observed upon immunodiffusion with certain pairs of antibodies. This may allow the use of pairs of monoclonal antibodies to LDL for the quantitative determination of apolipoprotein B in serum LDL and VLDL.
