General description
Bluo-Gal is a chromogenic substrate for β-galactosidase, used to determine the presence or absence of a cloned DNA insert in bacteria growing on agar plates. Bluo-Gal is designed to replace X-Gal in blue-white selection of recombinant bacterial colonies with the lac+ phenotype.
Application
Chromogenic substrate suitable for identification of lac+ bacterial colonies. An alternative to 5-bromo-4-chloro-3-indolyl β-D-galactopyranoside (X-Gal), producing a darker blue color.
Bluo-Gal is suitable for use in selection of recombinant bacterial colonies with the lac+ phenotype. Bluo-Gal is suitable for use as β-galactosidase substrate in the staining of skin tissues for electron microscopy analysis, Dictyostelium samples and in the staining of vena cava of adult mice.
Biochem/physiol Actions
When Bluo-Gal is hydrolyzed by β-galactosidase, the resulting product will form a blue precipitate. Lac+ colonies grown in the presence of Bluo-Gal turn a deeper blue color more intense than X-Gal, allowing for easy differentiation between lac+ and lac- colonies.

Taste buds are a heterogeneous population of cells exhibiting diverse morphological and biochemical characteristics. Because taste buds arise from multiple progenitors, the different types of taste cells may represent distinct lineages. The present study was undertaken to determine the following:
