title: Spectrophotometric quantitation of peroxidase-stained protein bands following gel electrophoresis and the western blot transfer technique with respiratory syncytial virus.
abstract: A procedure is described for spectrophotometrically measuring the position and intensity of ELISA-stained protein bands after western blot analyses. Partially purified virus proteins separated by acrylamide gel electrophoresis and electrophoretically transblotted onto nitrocellulose paper were identified by ELISA reactions according to established procedures. The nitrocellulose paper strips were then rendered transparent on glass slides by treatment with a plastics solvent (Gelman Sepra-Clear). The slides were then scanned at 480 nm to obtain the precise migration distance and area under the curve (i.e., quantity) of each band, thus allowing accurate comparison of the proteins from different virus strains.
