(Brilliant Blue G) Electrophoresis Grade Useful dye for SDS gels as it readily stains proteins with minimal background color. Protein bands can be visualized during staining. *Trademark of Imperial Chemical Industries, Ltd.

Sigma Aldrich - 27816

Application
For detection of protein bands following electrophoresis.
Other Notes
Protein stain for gel electrophoresis; 5 to 10 times more sensitive than Naphthol Blue Black B and Bromophenol (as little as 0.5 μg/cm2 of protein could be detected in a gel matrix)1,2

Sigma Aldrich - 379204

Application
For detection of protein bands following electrophoresis.

Sigma Aldrich - 75970

Application
For detection of protein bands following electrophoresis.

Sigma Aldrich - B6529

Components
0.5% (w/v) Brilliant Blue R, 45% (v/v) ethanol and 10% (v/v) acetic acid.
Analysis Note
Tested for suitability on agarose gels following immunoelectrophoresis.
Application
Brilliant Blue R staining solution is especially designed for use in staining protein in agarose gels following immunoelectrophoresis and Ouchterlony gels. The stain contains ethanol and acetic acid so gels do not require fixing prior to staining. The immunoelectrophoresis or Ouchterlony gel is first washed with water and saline to remove non-precipitated proteins and then dried. The gel is then immersed in staining solution for 30 min and destained with 10% acetic acid.
For detection of protein bands following electrophoresis.

Sigma Aldrich - B4921

Application
Detects most proteins at 50-100 ng per band
For detection of protein bands following electrophoresis.
Reconstitution
One tablet makes 400 mL of a 0.1% staining solution.

Sigma Aldrich - B8647

Application
Brilliant Blue R concentrate is a methanol based stain especially designed for staining protein in polyacrylamide but will also stain agarose gels. The stain contains methanol and acetic acid so gels do not require fixing prior to staining.
For detection of protein bands following electrophoresis.
Reconstitution
After dilution with deionized water to a final volume of one liter, solution will contain 0.25% (w/v) Brilliant Blue R, 40% (v/v) methanol and 7% (v/v) acetic acid.
