Immunochemical determination of human apolipoprotein B by laser nephelometry.
The Hyland laser nephelometer PDQ system for the assay of apolipoprotein B (apo-B) in human serum is described. Within and between-batch precision, accuracy and reliability are discussed. This instrument represents an important development in the immunochemical assay of apo-B, and the speed, precision, and convenience of the methodology make such a system attractive. Quantitation of apo-B was assessed in normal and hyperlipaemic subjects. Comparisons were made with two other specific and sensitive immunological methods for quantifying apo-B: enzymeimmunoassay (EIA) and rocket immunoelectrophoresis (RIE). Results obtained by the three methods correlated very well.
