  • Title: [Highly sensitive electroimmunodiffusion method of detecting antigens on cellulose acetate film].
    Author: Abelev GI, Sokolenko AA.
    Journal: Biull Eksp Biol Med; 1977 Jul; 84(7):121-4. PubMed ID: 70243.
    Abstract:
    A highly sensitive electro-immunodiffusion test suggested by the authors for antigen detection on cellulose-acetate films consists of three stages: antigen concentration in a discontinuous buffer system on cellulose-acetate films; antigen detection on the same films by immunodiffusion using standard test system; to detect the precipitation bands the washed films are stained with protein dyes in case the reaction takes place in the zone of vision, or subject to further treatment by means of "plating" the precipitates with antiglobulin antibody or by radioautography. The method permits one to reveal the nanogram levels of alfa-fetoprotein and it may be applied for detection of antigens with different molecular weights and electrophoretic mobility.
