afraGFP for cytosoloc expression

Characterisation via fluorescent measurement

The afraGFP (BBa_K4188034) and afraGFP_PTS1 (BBa_K4188006) were inserted into a level 1 shuttle vector, the pSB1KY-HIS3. The ScpTEF promotor and the ScCYC1 terminator were added to the coding sequence. 100 µl of a 1:5 diluted Saccharomyces cerevisiae suspension derived from cultures incubated for two hours were added to a well plate primed with concanavalin A. After 10 min of incubation, the S. cerevisiae suspension was replaced with Sc-all medium and the cells were imaged using a Nikon N-SIM microscope with an exposure time of 100 ms at 2 % laser intensity. AfraGFP fluorescence was excited at 488 nm and emission was detected at 510 ± 15 nm. Subsequent image editing in B allowed for better visibility of the cell background. Scale bar 5 µm.
