Brilliant Blue G is triphenylmethane dye that was developed for use in the textile industry but is now commonly used for staining proteins in analytical biochemistry. The Bradford assay is a standard, rapid dye-binding assay that uses Brilliant Blue G to quantify the amount of protein in a solution. Brilliant Blue G also acts as a selective inhibitor of the P2X purinoceptor channel P2X7 (IC50s = 10.1 and 265 nM for rat and human P2X7, respectively). In mice, it inhibits interleukin-1β expression and reduces neurological injury secondary to traumatic brain injury. Brilliant Blue G was used to prepare the protein reagent for the determination of protein content of the collagenase enzyme isolated from fish waste. It may be employed as a stain for the internal limiting membrane (ILM) for the macular hole (MH) and epiretinal membrane (ERM) surgery. — NCATS
