Coomassie Blue Stain: (for gels) 1) Combine 225 ml Methanol with 225 ml ddH2O. 2) Add 0.5 grams of Coomassie Blue. 3) Just before use, add 50 ml acetic acid to 10% final concentration. 4) Stain for 2 hours. Staining time can be shortened by microwaving; ~50 seconds at medium power. 5) After staining, pour off the stain into a bottle marked Used Stain. Stain can be re-used once, bu......閱讀全文
