Description
Bromocresol Purple (BCP) is a pH-sensitive dye widely used as a colorimetric pH indicator and analytical reagent. It exhibits a distinct color change from yellow at pH <5.2 to purple at pH >6.8, making it valuable in titrations, buffer preparation and biochemical assays. In clinical and laboratory settings, it is commonly used in protein and albumin assays due to its ability to form colored complexes under acidic conditions. In yeast it helps in dead cell count for cells with plasma membrane damage. Cells with proper cell membrane are not stained, while damaged cells are seen as blue-grey ghosts.
