    Synonym: 3-Amino-7-(diethylamino)-2-methylphenoxazin-5-ium (T-4)-tetrachlorozincate (2:1), Brilliant Blue C


    Application : 

    Brilliant Cresyl Blue has been used for the selection of oocytes. It has also been used for the selection of cumulus-oocyte complexes (COCs).
    Brilliant cresyl blue has been used for the staining of reticulocytes.


    Biochem/physiol Actions : 

    Brilliant Cresyl Blue is mainly used for the selection of oocytes. It helps in determining the activity of glucose-6-phosphate dehydrogenase (G6PD). This enzyme is generated in growing oocytes. However, oocytes which complete their growth have low levels of G6PD. Low G6PD activity results in blue coloration of the cytoplasm because brilliant cresyl blue is not reduced to a colourless compound. It is also used for the staining in reticulocytes, where the dye stains reticulin.
    Brilliant cresyl blue is responsible for the staining of RNA in reticulocytes.


    Other Notes : 

    The structure of Brilliant Cresyl Blue contains a 2-methyl modification on the phenoxazine core, while the structure of the historic Brilliant Cresyl Blue contains a 8-methyl modification on the phenoxazine core. The biological staining application is the same for both structures.

    Empirical Formula (Hill Notation)C19H10Br4O5S

    Synonym: 3′,3′′,5′,5′′-Tetrabromophenolsulfonephthalein, Bromophenol Blue (BPB), Bromphenol Blue Sultone Form


    Bromophenol blue is used as a pH indicator, a electrophoretic color marker, and a dye. It can be prepared by slowly adding excess bromine to a hot solution of phenolsulfonphthalein in glacial acetic acid.

    Application : 

    Bromophenol Blue has been used as a tracking dye for nucleic acid and protein electrophoresis in agarose and polyacrylamide gels.
    Bromphenol Blue is used as a tracking dye in DNA, RNA (agarose) and protein (polyacrylamide) gel electrophoresis. Bromophenol blue migrates at approximately the same rate as 300-500bp DNA in agarose gel and at the buffer front in protein polyacrylamide gels.
