Tetrabromophenol blue, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: 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 colour from pale green to blue. Binding of TBPB to proteins is dependent on pH.

Alcian blue solution, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Alcian Blue solution has been used in the histological staining of acidic glycosaminoglycans (GAGs; mucopolysaccharides) that are carboxylated or sulfated. Sulfated glycosaminoglycans appear to be the preferred substrate for alcian blue at pH 2.5. Alcian blue has been used to stain hyaluronan (HA), a nonsulfated GAG, but the intensity of the staining of HA is affected by the method of tissue fixation used. Alcian blue staining of GAGs in tissue may be modified through the addition of an electrolyte such as magnesium chloride.
