title: Double diffusion in gel reactions with antigens insoluble in aqueous media.
abstract: Ethanol-soluble, but saline-insoluble antigens were prepared as saline suspensions and studied in double diffusion reactions in a soft agarose gel. Positive reactions were observed with syphilis and SLE sera tested against the Kahn antigen as well as against commercial cardiolipin reagents. Also, ethanol-soluble brain antigen was studied for organ-specific reactions with rabbit immune sera. It was shown that double diffusion in gel can be employed as an analytical procedure for studies on reactions of saline suspensions of ethanol-soluble antigens.
