Fluorescent properties of amajLime

Instead of chromorptein, we proposed that amajLime is a fluorescent protein with the property of showing pigmentation, like BBa_E1010. We charaterised spectral properties of amajLime and found its max excitation and emission wavelength at 445 nm nd 485 nm respectively.

Charaterization of pH stability of amajLime

We grew C41 bacteria with parts BBa_K1033916 with constituitive promoter: J23100, in 2XYT for 24 hours. Purifying the amajLime by Ion Exchange Chromatography and Hydrophobic Interaction Chromatography, we measured the fluoresece of purified amajLime, which is diluted to 10µg/100µl (total 200µl) in triplicates, in different buffers (ranges from pH2 to pH12). The result shows that the stability drops dramatically in condition below 6 and attains maxima fluorescence at pH 8.
