Bioworld Coomassie Blue G-250 (2X), 500 mL
A commonly used analytical biochemistry dye and P2X7 antagonistStain for location and detection of proteins. Protocol: After SDS-PAGE, transfer the gels in fixing solution (30% methanol and 7% acetic acid) for 30 min. under constant agitation. Replace the fixing solution, submerge the gel in stain and shake the gel gently gor 2-4 hrs. Pour off the stain, rinse the gel briefly with fixing solution and cover the gel with fresh fixing solution for 30 min. Repeat and continue destaining until distinct blue bands against a clear background are obtained. Store the gel in 7% acetic acid solution. Photograph or dry the gel according to your standard protocol.Synonym: Synonym: Acid blue 90, Coomassie Brilliant Blue GAppearance: LiquidHS Code : 32041200
Bioworld Coomassie Blue R-250 (2X), 500 mL

Bioworld Coomassie Brilliant Blue R-250, 10 g
Protein electrophoresis dye used in SDS-PAGE.More sensitive than G-250.Ultra Pure GradeEM (550nm, water) >33,000Protein Staining: PassesAppearance: Solid
Bioworld Express Coomassie Stain, G-250, 500 mL
Express Coomassie Stain detects as little as 15 ng of protein and gives complete band detection within 50 minutes. Its ideal for densitometry and its able to be restained with silver. This stain can be used more than once. Express Coomassie is a colloidal suspension of Coomassie blue that preferentially binds to protein and eliminates the unwanted destaining step. Available in both R-250 and G-250.Appearance: LiquidHS Code : 32041200Melting Point: 100 °C
