LSSmOrange is an orange fluorescent protein that we want to use for FRET, we us it as a donor. LSSmOrange has an excitation maximum by 437 nm and an emission maximum by 572 nm.  The excitation maximum is at 415 nm, another at 453 nm and our measured emission maximum is at 564 nm (Fig. 2). This aberration changes nothing on the FRET system. The excitation maximum is big enough to stimulate [https://parts.igem.org/Part:BBa_K1055000 mKate], the other fluorescent protein (Fig. 3). Of course, we also checked the emission and excitation of our ''E. coli'' BL21(DE3) cells (data not shown) and we can eliminate the theories that these cells disturb this florescence measurement.

LssmOrange is a fluorophor derived from dsRed and is a FRET partner of mKate [BBa_K1055000]


Usage and Biology

Figure 1. Pellet of E. coli BL21 (DE3) cells with expressed LSSmOrange. Left side without UV radiation, right side with UV radiation

LSSmOrange is an orange fluorescent protein that we want to use for FRET, we us it as a donor. LSSmOrange has an excitation maximum by 437 nm and an emission maximum by 572 nm. The excitation maximum is at 415 nm, another at 453 nm and our measured emission maximum is at 564 nm (Fig. 2). This aberration changes nothing on the FRET system. The excitation maximum is big enough to stimulate mKate, the other fluorescent protein (Fig. 3). Of course, we also checked the emission and excitation of our E. coli BL21(DE3) cells (data not shown) and we can eliminate the theories that these cells disturb this florescence measurement.
