Application of stains-all staining to the analysis of axonemal tubulins: identification of beta-tubulin and beta-isotubulins.


PMID 1704028

Abstract

The cationic dye, Stains-all, is known to stain brain beta-tubulin blue and alpha-tubulin red (Serrano, L. et al. (1986) J. Biochem. Biophys. Methods 12, 281-287; Serrano, L. et al. (1989) Biochem. Int., 19, 235-246). The present experiments show that this stain can also be applied to detect beta-tubulin in axonemal tubulins from various sources such as cilia of protozoa, sperm flagella of echinoderm, and sperm flagella of mollusc. Furthermore, these experiments showed that it selectively stains isoforms of axonemal beta-tubulin blue following isoelectric focusing, whereas those of alpha-tubulin are stained red. These results indicate that Stains-all staining is a useful tool for electrophoretic analysis of axonemal tubulins.
