Medchemexpress LLC Brilliant blue G-250 | 6104-58-1 | 92.05% | 100 MG

Brilliant Blue G-250 is a dye primarily utilized for visualizing proteins separated by SDS-PAGE, providing a simple staining procedure and high quantitation. It is also effective in the Bradford protein assay, where protein concentrations are determined by its absorbance at 595 nm due to protein binding. Additionally, it functions as a safe and highly selective P2x7R antagonist, which leads to the inactivation of the NLRP3 inflammasome.

Visualizes proteins separated by SDS-PAGE.
Offers simple staining procedure.
Provides high quantitation in protein analysis.
Determines protein concentrations in Bradford protein assay.
Acts as a selective P2x7R antagonist.
Inactivates NLRP3 inflammasome.
Functions as a fluorescent dye and indicator.
Suitable for histological analysis.
Useful as a biochemical assay reagent.
