Synthetic Acrylic Gel: A New Medium for the Study of Immune Precipitates

Abstract

The physicochemical properties of photocatalyzed Cyanogum gel offer practical advantages in the analysis of specific immunological precipitation techniques: use of any buffer at any pH; most probable neutrality for stains or reagents; remarkable resolution of the immunological precipitates, visible microscopically; possibility of direct dark-background examination of the precipitates, so that their kinetics can be studied and they can be photographed before dyeing and staining. This gel seems particularly suitable for immunoanalysis of complex and unstable antigenic products, such as tissue homogenates.
