The PAAGE or SUGE patterns in the first dimension were allowed to migrate by PAGIF in an orthogonal direction giving rise to two-dimensional (2-D) separations. Using this procedure, some individual bands considered to be homogeneous by SUGE or PAAGE were found to be complex mixtures of casein components. A detailed analysis of the analytical capabilities of SUGE and PAAGE was performed. Procedures based on the densitometric reading of SUGE and PAAGE patterns seemed to give inaccurate results on the quantitative composition of caprine casein. Among the electrophoretic methods assayed, the 2-D procedure gave the best resolution of casein fractions.  aCasein  aGel electrophoresis  aGoat milk  aCaprino  aCaseína  aLeite de cabra  aEletroforese em gel1 aMAURIELLO, R.1 aDI LUCCIA, A.  tJournal of Dairy Researchgv. 55, n. 3, p. 413-421, Aug. 1988.
