sfBFP
Superfolder Blue Fluorescent Protein is a derivative of superfolder Green Fluorescent protein. Compared to eBFP it displays improved stability and strong blue fluorescence. Excitation peak: 380 nm Emission peak: 440 nm
Team Warsaw 2013 measured sfBFP 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.
