Immunological identification of complex proteins resolved by sodium dodecyl sulfate polyacrylamide disc gel electrophoresis.
Immunological identification of an antigen resolved from a protein complex by sodium dodecyl sulfate polyacrylamide gel electrophoresis has been attained. The identification is based on the formation of immunoprecipitin lines after the antigen diffuses laterally from acrylamide gel transverse slices into a surrounding agarose gel. This technique was designed for study of contractile and regulatory protein complexes of non-muscle cells where the scarcity of tissue precludes easy purification or high yield of muscle-like proteins. It complements double-gel immunodiffusion or immunoelectrophoresis and its use may be extended to other protein complexes.
