GelCode Blue Stain Reagent is a ready-to-use protein stain based on colloidal Coomassie dye G-250 that detects nanogram-level proteins in polyacrylamide gels and in blots.

Features include:
• No need for methanol-acetic acid destaining
• Fast one-step staining in one hour, ready-to-use staining reagent; Band formation is observed in the staining tray; no background from overnight staining; flexible fixation and washing protocols; no gel shrinkage; stained gels can be dried
• Water washing improves staining sensitivity; optional step Provides a clear and transparent gel background, making weakly stained bands more visible

GelCode blue staining reagent only stains proteins, making the bands visible directly in the gel during the one-hour gel staining process. Since the destaining step does not fix the protein, GelCode Blue stain is compatible with mass spectrometry and N-terminal sequence analysis.
