Detection of lipopolysaccharides in Polyacrylamide gels by transfer to nitrocellulose followed by immunoautoradiography with antibody and /sup 125/I-protein A: LPS blotting. [Gram negative bacteria]

Journal Article · · Anal. Biochem.; (United States)

Lipopolysaccharides (LPS), which constitute the somatic (O) antigen of gram-negative bacteria, were used to demonstrate the procedure of LPS blotting involving the electrophoretic transfer of electrophoretically resolved LPS from sodium dodecyl sulfate-polyacrylamide gels to nitrocellulose filters. Immobilized LPS could then be immunoautoradiographically visualized in situ by reaction with specific anti-LPS antibody and subsequent binding of radioiodinated Staphylococcus protein A. LPS blotting is expected to provide an efficient and specific means of investigating the LPS (O) antigens of gram-negative bacteria. 18 references.
