Biochem/physiol Actions

Tetrabromophenol Blue (TBPB) belongs to the group of sulfonephthalein acid-base indicators. It is employed in the potentiometric titration of the halogens with Hg2(NO3)2. In addition, it has been used as a dye indicator in urine dipstick test to detect proteinuria. In this assay, with increasing concentration of urinary protein, TBPB sequentially changes color from pale green to blue. Binding of TBPB to proteins is dependent on pH.

The facile detection of phosphopeptides is important for clinical screening and phosphoproteomic research. This work develops an instrument-free, cost-effective, convenient paper-based method for quantitative analysis of phosphorylated peptides. With a novel portable device, Phos-PAD, this method can achieve selective enrichment
