[Antigenic spectrum of identified edible snail neurons].

It has been shown that brain-specific protein--antigens can be examined by the unidimensional counter immunodiffusion techniques in the capillaries. In order to determine microamounts of the antigen, immunoprecipitation was performed in the capillaries filled with agarose gel (3 mm long, 0.3 mm in diameter). The antigenic profiles of identified neurons of snail have been analyzed comparatively.
