    Radial Immunodiffusion - an overview | ScienceDirect Topics

    Radial Immunodiffusion. The radial immunodiffusion (RID) is based on the precipitation of antigen and antibody to an insoluble precipitin complex and thus directly measures IgG concentration in serum or plasma. The RID is considered the reference method to measure serum/plasma IgG, but it takes at least 24 h to perform and thus longer than is ...
