One bottle of the product makes 1 liter of working solution. The suspension will contain 0.1% (w/v) Brilliant Blue G, 0.29 M phosphoric acid and 16% saturated ammonium sulfate after diluting to 1 Liter with 800 mL water.
Once diluted the solution should be stable indefinitely. It should be stored in the refrigerator and shaken well before each use. The solution tends to precipitate on standing and heat accelerates precipitation. Therefore, do not leave the bottle at room temperature overnight.
Use with nitrocellulose is not recommended, due to the methanol.
The major advantage of the colloidal form is that it gives less background staining that the "regular" non-colloidal Coomassie Brilliant Blue G and Brilliant Blue R stains. Sensitivity can be markedly increased by double staining, first with Coomassie Brilliant Blue G Colloidal, then Rapid Silver Stain.
The detection limit for proteins is about 50 ng of protein. However, proteins pick up stains differently so this is a general description and may not apply to all proteins
