Abstract
Enzyme-linked sandwich immunosorbent assay for serum myoglobin with 3 monoclonal antibodies to different epitopes is described. Antibodies 13G6 and 18H2 were adsorbed on a carrier, and 14D6 antibodies were labeled with horseradish peroxidase. One-step incubation with standard myoglobin solution yielded double sandwich: adsorbed antibodies—myoglobin—labeled antibodies; the intensity of peroxidase reaction was directly proportional to myoglobin concentration. The sensitivity of the proposed method for serum myoglobin was below 5 ng/ml. The sensitivity of the method increases due to myoglobin binding with two antibodies adsorbed on the carrier. Fluctuations within and between series did not exceed 10%.
