| Coomassie Brilliant Blue G-250 | AppliChem | A3480 | any other CBB G-250 could be used as well |
| Concentrated HCl |
This is very clear and easy way of staining the gels. I would like to know the consequences of using acetic acid and organic solvents in staining the proteins electrophoresd using polyacrylamide gels, or what was is this method advantageous than the traditional coomassie staining using acetic acid and methanol ?
your replies are appreciated

Rajesh
