RESUMO
To characterize the specificity of monoclonal antibodies against respiratory syncytial virus, we developed a technique which combined the biotin-avidin system, immunoprecipitation, and transblot electrophoresis. The viral proteins were first biotinylated and then immunoprecipitated with a monoclonal antibody or respiratory syncytial virus immune serum, separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and electrophoretically transferred to nitrocellulose paper. The protein bands were located on the paper with avidin-peroxidase plus a precipitable substrate. This procedure gave reproducible results qualitatively similar to those obtained by radioimmunoprecipitation but without the cost, risk of radiation exposure, or disposal problems of radioisotopes. This procedure should have widespread applications.
