Fluorescent properties of amajLime Instead of chromorptein, we proposed 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. Fig.1 Emission and Excitation spectra Charaterization of pH stability of amajLime We grew C41 bacteria with parts BBa_J61002 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 7 Fig.2 Vary pH attributed to different fluorescent intensity of RFP.
