Plasmids from Article

ID Plasmid Purpose
184225SpySwitchExpresses SpySwitch in the bacterial cytoplasm. SpySwitch binds SpyTag-, SpyTag002- or SpyTag003-fusions non-covalently for affinity purification, allowing gentle pH or temperature release.
184226SpyTag-sfGFPExpresses SpyTag-superfolder GFP in the bacterial cytoplasm. SpyTag enables covalent reaction with SpyCatcher.
184227AviTag-SpyTag003-MBPExpresses AviTag and SpyTag003 linked to maltose binding protein in the bacterial cytoplasm. AviTag enables site-specific biotinylation by BirA. SpyTag003 enables reaction with SpyCatcher003.
