title: Analysis of alpha-fetoprotein heterogeneity by an improved crossed immunoaffinoelectrophoretic technique.
abstract: The crossed immunoaffinoelectrophoretic procedure described here for the analysis of alpha-fetoprotein heterogeneity includes three major modifications of a procedure previously used by others: impregnation of the second dimension gel with methylated sugar derivatives; rigorous gel washing at 37 degrees C with the same derivatives; and an immunostaining technique. These simple changes have resulted in clear, sharp electrophoretic patterns at levels of total alpha-fetoprotein as low as 50 ng/ml, a sensitivity not previously approached with the method. Individual peaks representing as little as 7.5 ng/ml can be identified.
