Radial immunodiffusion (RID) is a technique that can quantitatively. determine the concentration of an antigen. Unlike many gel and liquid. precipitation techniques which qualitatively detect antigen, RID is a. sensitive quantitative technique that is often used clinically to detect. patient levels of blood proteins.
Photodynamic therapy apparatus providing improved light distribution with an end fitting for use with clad optical fibers, which apparatus cooperates with an unclad stripped terminal end of the optical fiber that is inwardly tapered towards its end such that light scattering media disposed between a glass tube surrounding at least the tapered ...
