The Colloidal Blue Staining Kit allows detection of nanogram levels of protein with minimal effort and requires only water to destain. With the Colloidal Blue Staining Kit, you get:

Five times more sensitivity than Coomassie® R-250—detect as little as 10 ng of BSA

Easy-to-use, mass spectrometry–compatible reagents

Great densitometry resultsThe Colloidal Blue stain uses colloidal chemistry that reduces free dye in solution and improves the protein-to-dye binding ratio. Samples are intensely stained and visible within 3 hours. Background staining is virtually eliminated by destaining overnight with water. The kit requires one easy solution preparation. Methanol is required in the staining step, but is not included in the kit.
