sfYFP

Superfolder Yellow Fluorescent Protein is a derivative of superfolder Green Fluorescent protein. Compared to eYFP it displays improved stability and strong yellow fluorescence. Excitation peak: 503 nm Emission peak: 540 nm

Team Warsaw 2013 measured sfYFP 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.

Also Team Warsaw 2013 measured SYFP2 (BBa_K864100) and compared it with sfYFP.
