Abstract
The application of immunogold for the detection of antigen-antibody complexes on nitrocellulose paper is described. Tobacco mosaic virus (TMV) protein, either purified or in leaf extract, was bound to the nitrocellulose paper and then exposed to rabbit anti-TMV serum. The antigen-antibody complexes were detected by gold-labeled goat anti-rabbit immunoglobulin G. The gold-labeled antibody is directly visible because of its pink color. This method can detect 1-5 pg of TMV protein, either in purified form or in the unpurified plant extract, with high specificity.Entities:
