RAPIDstain™ protein stain
G-Biosciences' RAPIDstain™ is an ultra sensitive, ready-to-use protein stain based on Coomassie dye

  • Ultra sensitive: 4-8ng BSA
  • Time Saving: band develops in 5-10 minutes
  • Single step method
  • No methanol or acetic acid destaining agents

G-Biosciences' RAPIDstain™ only stains protein, leaving a crystal-clear background resulting in high band visibility. The gels require no destaining. The protein band intensity is enhanced by simply rinsing with water. RAPIDstain™ has the sensitivity to detect as little as 4-8ng BSA. Staining shows a linear response for densitometric gel analysis and produces sharp scanning or photographic results.

G-Biosciences' offers RAPIDstain™ in a 1 liter supply, sufficient for staining up to 50 mini gels (8 x 10cm) and a 1 gallon supply, for staining up to 200 mini gels. No methanol or acetic acid destaining agents. RAPIDstain™ is suitable for native, denaturing, isoelectric focusing, and 2D gels.

No mixing or preparation is involved. No fixation step is needed. Simply rinse gel, add RAPIDstain™, and protein bands develop within 5-10 minutes, reaching maximum visibility in one hour. Mini-gels can be stained in 10 minutes.
