Coomassie Brilliant Blue R-250 & G-250 Dyes
Ideal as a protein stain following electrophoresis.
Highlights:
- Develops intensely colored complexes with proteins
- Can determine as little as 0.5 µg/cm2 of protein present in a gel matrix
- Anion of Coomassie Brilliant Blue formed in the acidic staining medium combines with the protonated amino groups of proteins by electrostatic interaction; resulting complex is reversible under the proper conditions
- When dissolved in 0.01 M citrate buffer at pH 3.0, has an absorption maximum at 555 nm; protein-dye complex is characterized by a peak slightly broader than that of the free dye with a maximum at 549 nm
