title: Analysis of tubulin isoforms by two-dimensional gel electrophoresis using SDS-polyacrylamide gel electrophoresis in the first dimension.
abstract: A two-dimensional electrophoretic system using SDS-polyacrylamide gel electrophoresis (SDS-PAGE) in the first dimension and isoelectric focusing (IEF) in the second dimension was devised. In spite of its simplicity, this method could show a markedly high resolution for tubulin isoforms and moreover could classify them into alpha- or beta-tubulin as a two-dimensional profile. With this method, seven alpha- and four beta-tubulin isoforms could be detected within axoneme from Tetrahymena cilia. Moreover this method could also resolve tubulin isoforms from the rabbit brain. These results indicate that the present two-dimensional gel electrophoresis is a useful tool for the electrophoretic analysis of tubulin isoforms from various sources.
