sfCFP

Superfolder Cyan Fluorescent Protein is a derivative of superfolder Green Fluorescent protein. Compared to CFP it displays improved stability and strong cyan fluorescence. Excitation peak: 425 nm Emission peak: 475 nm

Team Warsaw 2013 measured sfCFP and other designed superfolder proteins and compared them to sfGFP (BBa_I746908). Measurment was conducted on pSB1A3 plasmid with J23100 promoter and B0034 RBS in living cells in RF.
