Abstract:
:An enzyme-linked immunosorbent assay was developed for quantitation of complement C3b receptors (C3bR) on human erythrocytes fixed in monolayer to microtiter plates. The disadvantages of macro test tube systems (large consumption of sample material and reagents, tedious washing procedures, cell loss and hemolysis) were avoided, and the fixed cells could be stored. In return a modest reduction in antigenicity induced by glutaraldehyde was inevitable. The calibration curve expressed a detection limit of about 10% and discrimination between levels of C3bR in the interval of about 10-120% of a standard erythrocyte with a high uptake of anti-C3b-receptor antibodies. The determinations of C3bR in normals as well as in patients varied within these limits, and showed a preponderance of low levels in the patients. The between-day coefficient of variation was 10.3%; the within-assay interplate and intraplate determinations respectively gave coefficients of variation of 9.7% and 6.2%. The method is suitable for further development and use for investigation of erythrocyte-bound immune complexes.
