InstantBlue™ ready to use Coomassie protein stain for polyacrylamide gels
InstantBlue™ is a ready to use Coomassie protein stain for polyacrylamide gels. Its unique mechanism of action stains proteins in 15 minutes while leaving a clear background eliminating the need to fix, wash or destain. Formulated for safe use and easy disposal, its ready for use straight out of the bottle and comes in convenient pre-mixed 1 litre volumes. Perfect for use with the InstantBlue™ Stain Tray.
The unique patented mechanism for rapid Coomassie blue staining of protein gels begins in moments, and results are achieved within 15 minutes. Some premade and traditional home-made Coomassie R-250 protein stains can take 3 hours or more to fully stain gels.
Why InstantBlue™ Protein Stain?
There’s no need to wash, fix, microwave or destain gels when using InstantBlue™. Homemade stains often require all these steps and most premade solutions require at least one. InstantBlue™ uses a simple and easy to use one-step protocol.
Unparalleled sensitivity allows protein levels as low as 5 ng per band to be detected (BSA) when staining overnight. This is thanks to InstantBlue™’s protein-specific staining which gives a clear background, improving the signal/noise ratio of the stain. Despite the staining power, gels can be left in InstantBlue™ for weeks and still come out with a crystal-clear background, all without the need for destaining or protein stain remover.
The non-toxic formula is sink disposable and thanks to its methanol free composition will not shrink gels. Other stains require solvent disposal procedures and can require microwaving which produces dangerous fumes. The effective staining and safe composition of InstantBlue™ means there’s no need for microwaving, solvent disposal, or fume hoods.
InstantBlue™ will stain at least 40 mini-gels per bottle, boasting economical staining with only 25ml per mini-gel. As a result, this allows you to use less protein staining solution when compared to 50-100ml of stain per gel for homemade solutions and some pre-mixed solutions.
Fully compatible with Mass Spectrometry, can be destained using standard procedures. The protein staining solution’s acetic acid-free formulation means it will not methylate or acetylate protein during the protein staining protocol.
