Here, we describe an innovative method to determine complement receptor 1 (CR1) length polymorphisms for use in several applications, particularly the assessment of susceptibility to diseases such as Alzheimer's disease (AD). This method could be useful to better understand the role of CR1 isoforms in the pathogenesis of AD.

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).
