Quantitative electrotransfer of proteins from sodium dodecyl sulfate-polyacrylamide gels onto positively charged nylon membranes.
A method for the reproducible and quantitative electrotransfer of proteins from sodium dodecyl sulfate-polyacrylamide gels to a single sheet of either Zetabind or Gene Screen Plus membranes is presented. This procedure uses commercially available equipment and includes three crucial parameters: the omission of methanol from the transfer buffer, the use of thin (0.75-mm) resolving gels, and a newly developed protocol for pretreatment of the polyacrylamide gel after electrophoresis and before electroblotting. This combination of parameters yields a blot that both qualitatively and quantitatively reflects the proteins in the original polyacrylamide gel.
