How many times can a gel stained with SYPRO Ruby be scanned without decay of the fluorescent signal?


SYPRO Ruby Protein Gel Stain (1703126, 1703125 and 1703138) is fairly resistant to photobleaching (as compared to other dyes like fluorescein and Nile Red). SYPRO Ruby-stained gels may be scanned repeatedly with little or no loss in sensitivity. Photobleaching occurs after 10–15 minutes of continuous exposure to a 20 W UV box. Gels should not require restaining, but restaining will not cause any problems or produce any artifacts.
