Thermo Scientific GelCode Blue Safe Protein Stain is a fast and sensitive coomassie-dye reagent that provides one-step ultrasensitive detection of proteins in polyacrylamide gels and is formulated to avoid hazardous shipping costs.

GelCode Blue Safe Protein Stain is a coomassie G-250 dye-based reagent for staining protein on polyacrylamide gels and membranes. GelCode Blue Safe Stain provides considerable sensitivity, allowing for the detection down to 9ng of protein. This protein-specific stain allows bands to be viewed directly on a gel or membrane during staining and is compatible with mass spectrometry applications. The staining process is simple and flexible, usually requiring a 15-minute incubation of the gel or sample with the GelCode Blue Safe Protein Stain, followed by a simple water wash to yield blue protein bands and a clear background.

Because the supplied Activator Crystals are packaged and shipped dry in a separate bottle, GelCode Blue Safe Protein Stain is classified as nonhazardous under the U.S. Department of Transportation （DOT） shipping requirements.

Highlights:

• Sensitive and fast – detect down to 9ng of protein per band in 15 minutes
• Safe – non-corrosive to skin, non-flammable and safe to ship and store until activated
• Convenient – water washes only; no acid-fixative or methanol destain solutions required
• Versatile – suitable for staining 1D and 2D polyacrylamide gels, nitrocellulose and PVDF membranes （multiple protocols provided in the instructions）
• Compatible – useful for qualitative visualization, quantitative densitometry, and downstream excision and analysis by mass spectrometry
• Easy to use – add and dissolve activator crystals before first use, then simply add reagent to stain gels
• Stable – store non-activated or activated stain at room temperature for up to one year
