Could anyone please let me know the differences between Comassie-R-50 and Comassie-G. One of our protocols to detect multiprotein complexes from mitochondria needs coomassie-R. If you know the source (company) of getting this compound in US, let me know. -Dinakar -- Dinakar Bhattramakki/Ph.:(402) 472-6243/email:ddh at unlinfo.unl.edu
