Triphenylmethane dye-type indicators are a class of organic color-change reagents based on triarylmethane or related lactone/quinoid structures. They are widely used in acid-base titration, non-aqueous titration, complexometric titration, protein assays, histological staining, microbiological ...
In many laboratory workflows, reagents whose names include “blue” are used for tracking, staining, or colorimetric readouts. Despite similar naming, their molecular targets, signal-generation mechanisms, and susceptibility to interference differ substantially. Background elevation, unstable ...
How can I quickly remove the bromophenol blue that may be obscuring the bands at the end of the gel run?
Protein samples boiled in buffer are blue in color and turn blue-violet after being left at -80°C. What is the reason for this? Does it affect the subsequent electrophoresis?
