Verwenden
Bromocresol purple has been used as a pH indicator in the yeast culture media. It has been used as a pH indicator in the culture media of
Geobacillus stearothermophilus subsp.
Calidolactis.
Definition
ChEBI: A member of the class of 2,1-benzoxathioles that is 2,1-benzoxathiole 1,1-dioxide in which both of the hydrogens at position 3 have been substituted by 3-bromo-4-hydroxy-5-methylphenyl groups. A hydrophilic dye that is used as a pH indicator and to measure
serum albumin concentrations.
Allgemeine Beschreibung
Bromocresol purple is a pH indicator, which changes color from yellow (at low pH 5.2) to violet (above pH 6.8). It aids in determining the dead cell count for cells with plasma membrane damage. Bromocresol purple is widely used as a fluorescent stain in yeast cells. Cells with an intact plasma membrane are not stained, while damaged cells are seen as blue-grey ghosts.
läuterung methode
Dissolve the dye in aqueous 5% NaHCO3 solution and precipitate it from a hot solution by dropwise addition of aqueous HCl. Repeat this until the UV/VIS-extinction did not increase at 419nm. It can also be recrystallised from *benzene. It is an indicator: at pH 5.2 (yellow) and pH 6.8 (purple). [Beilstein 19/3 V 460.]
