Summary
The aim of this method is to determine the CR1 density in the erythrocytes of any subject by comparing with three subjects whose erythrocyte CR1 density is known. The method uses flow cytometry after immunostaining of the subjects' erythrocytes by an anti-CR1 monoclonal antibody coupled to an amplified system using phycoerythrin (PE).
