In addition, it has been used as a dye indicator in urine test strips to detect proteinuria. In this measurement, as the concentration of urinary protein increases, the color of TBPB changes from light green to blue in sequence. The binding of TBPB to proteins is related to pH. Usage: Bromophenol blue indicator solution. Usage: Color changing range: pH 2.8-4.6 (yellow blue), acid-base indicator; Non aqueous titration indicator, protein electrophoresis staining; Virus testing, etc. Used as a pH indicator for weak acids and weak bases, with a color change from yellow (6.0) to blue (7.6), to observe photosynthetic activity or respiratory indicators, and as a biological slide staining agent for detecting cell nuclei or cell walls
