FaStain is a Coomassie Brilliant Blue dye based protein staining solution which provides a fast, convenient and sensitive method for staining proteins separated in both native and SDS-PAGE gels. The staining procedure is very straightforward — just simply incubate gels in the staining solution until protein bands are developed. The procedure requires 15 minutes of washing and 15 minutes of staining. It takes only 30 minutes to detect as little as 5 ng of protein on a water-clear background.

• Convenient -
  Ready-to-use


• Simple -
  One-step, no destaining step required


• Fast -
  30 minutes for standard staining procedure (3 × 5 minutes washing & 15 minutes staining)


• Sensitive -
  More sensitive than Coomassie Brilliant Blue R-250, 5 ng of protein can be detected.


• Safe -
  No methanol or acetic acid


• Money saving -
  Can be reused up to 3 times

• For both native PAGE or SDS-PAGE gels
• Excellent for densitometry for visualization and quantification
• Compatible with mass spectrometry
• Protein staining after transfer onto PVDF membranes.

• The signal of can be visualized within 5 minutes, and achieve to maximum in 30 minutes.
• To enhance sensitivity and reduce background, wash the gel with water from 1 hour to overnight after staining.

Standard protein BSA (1 - 1000 ng) in different amounts were electrophoresed on 12% Tris-glycine SDS gel. Minimum 10 ng BSA should be detected by the staining in a clear background.
