Wheat germ agglutinin (WGA) precipitates bone type serum alkaline phosphatase (sALP) isoenzyme specifically. The precipitates are composed of the macromolecules of WGA and "bone type sALP" (WGA-ALP complex). In order to use bone type sALP as a marker in polyacrylamide gel electrophoresis (PAGE), a method to separate "bone type sALP" from the "WGA-ALP complex" was established by using N-acetyl-D-glucosamine (GlcNAc)-Sepharose 6B column chromatography. It was concluded that this method is useful for clinical examination in the rat.
