  • Detection and quantitation of radiolabeled proteins

    Abstract. This appendix presents procedures for visualizing and quantitating radiolabeled proteins or DNA separated by polyacrylamide gel electrophoresis or affixed to filter membranes. Autoradiography is the most common method by which this is accomplished; X-ray film is the traditional recording medium.

    1991-9-13 · Polyacrylamide gel electrophoresis (PAGE) and staining of proteins is relatively easy to perform, but quantification of separated proteins is often necessary. It is quite easy to measure stained protein bands with a densitometer, however, it is much more difficult to evaluate the measured absorbance and to obtain reliable quantitative data reflecting the amount of the protein actually present.
