Antigen-antibody reaction studied by laser light scattering

Static light scattering (SLS) has been used to study the antigen-antibody reaction in buffer medium. B-group blood was mixed with its antibody and the clustering studied using static laser light scattering technique. A home made scattering set up has been used and the clusters formed were modeled as dasiafractalspsila with fractal dimension Df. The static Structure factor, Correlation length (xi) and the radius of gyration Rehave been determined assuming a Gaussian distribution for cluster size and a Gaussian cut off function for the cluster boundaries..
