General description

Brilliant Blue G is a methanol based stain which is especially designed for staining protein in polyacrylamide gels, but will also stain protein in agarose gels (IEF). The stain contains methanol and acetic acid so gels do not require fixing prior to staining. Water is added directly to the bottle to produce 1 liter of ready-to-use staining solution.


Brilliant Blue G solution has been used for protein band detection after SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis). It is also used for the protein staining of cells on microscopic slide.


1 ea in poly bottle


One bottle equals one liter working solution. 300 ml of brilliant blue G solution concentrate is supplied in the bottle.


After dilution with deionized water to a final volume of one liter, solution will contain 0.1% (w/v) Brilliant Blue G, 25% (v/v) methanol and 5% (v/v) acetic acid.

Analysis Note

This product has been tested for suitability on SDS-PAGE.

Exosomes are extracellular vesicles (EVs) of ~20-200 nm diameter that shuttle DNAs, RNAs, proteins and other biomolecules between cells. The large number of biomolecules present in exosomes demands the frequent use of high-throughput analysis. This, in turn, requires technical replicates

The proteomics field has shifted over recent years from two-dimensional gel electrophoresis (2-DE)-based approaches to SDS-PAGE or gel-free workflows because of the tremendous developments in isotopic labeling techniques, nano-liquid chromatography, and high-resolution mass spectrometry. However, 2-DE still offers the highest
