Blotting intact immunoglobulins and other high-molecular-weight proteins after composite agarose-polyacrylamide gel electrophoresis.
A composite agarose-polyacrylamide gel containing urea and sodium dodecyl sulfate reliably resolved unreduced human immunoglobulins according to their molecular weight. Intact immunoglobulins and a number of other macromolecules were readily transferred to nitrocellulose paper by either capillary or electrophoretic blotting, although the latter technique was more effective. Conventional antigen probing as well as immobilized antibody studies can be performed on the nitrocellulose transfers.
