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.

Sensitivity—detect down to 9 ng of protein per band in 15 minutes
Safety—non-corrosive to skin, non-flammable, and safe to ship and store until activated
Additional reagents—water washes only; no acid-fixative or methanol destain solutions required
Compatibility—suitable for staining 1D and 2D polyacrylamide gels and nitrocellulose and PVDF membranes (multiple protocols provided in the instructions)
Applications—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

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. For proper protein staining, the activator crystals must be dissolved in the staining reagent before use. Add the entire contents of the activator crystals bottle into the GelCode Blue Safe Protein Stain bottle. Dissolve the crystals by mixing end-over-end for one minute, and then allow it to remain at room temperature for five minutes before use. Store the activated stain at room temperature.
