A study of alkaline phosphatase isoenzyme electrophoresis on cellulose acetate compared with agar, agarose and acrylamide in the presence or absence of triton X-100.

The application of Triton X-100 in cellulose acetate electrophoresis and its effects on the separation of serum alkaline phosphatases is described. The cellulose acetate electrophoretic patterns of serum alkaline phosphatase found in liver and bone disease have been compared with the patterns found in agar, agarose, and polyacrylamide gel in the presence and absence of Triton X-100 and the differences described and discussed. Changes in the alkaline phosphatase electrophoretic pattern and the effects on certain electrophoretic variants have been noted following addition of Triton X-100 to all parts of the system.

Correlation of apparent molecular weight and antigenicity of viral proteins: an SDS-page separation followed by acrylamide-agarose electrophoresis and immunoprecipitation.

A simple method is described which combines a sodium dodecyl sulfate polyacrylamide gel electrophoresis (SOS-PAGE) in the first demension with a second electrophoresis, at right angles to the first, into an agarose matrix. The proteins, separated by SDS-PAGE, are exposed to appropriate antisera after the second stage electrophoresis and immunoprecipitates form in the agarose corresponding to the relative electrophoretic mobilities of proteins in the first stage SDS-PAGE separation. The method thus provides a simple, reproducible means for correlating antigenicity with apparent molecular weight of proteins. The technique is qualtitative, but requires smaller quantities of antisera than more conventional immunoelectrophoretic methods such as rocket electrophoresis.
