Features

Clear visible protein staining in just 1 hour, no destaining required
One-Step Blue® produces fast (5-60 min) protein staining in a single step without fixation or washing. Destaining is optional. One-Step Blue® has comparable sensitivity as the widely used Coomassie Blue, with a lower limit of detection around 10-20 ng depending on the detection method used. Note that staining intensity varies between proteins. The staining is fully compatible with mass spectrometry and Edman-based sequencing. Proteins can be detected by visible blue staining, or by near-infrared fluorescence.

Results are clear. One-Step Blue® is a superior alternative to Coomassie and other colorimetric protein gel stains.
In a comparison experiment with Coomassie Brilliant Blue R-250 and Simply Blue™ SafeStain, One-Step Blue® demonstrated much clearer staining after 1 hour of destaining in water compared to other stains.

One-Step Blue® is non-toxic
One-Step Blue® offers safer handling and disposal compared to Coomassie staining because it is entirely aqueous-based, without hazardous methanol or acetic acid. One-Step stains are certified under CCR Title 22 as non-toxic to the environment for drain disposal after a simple pH neutralization step.
