Cellular imaging made easier: Scientists modify a protein to exhibit the shortest fluorescence emission wavelength osaka_univ CommsBio
. Because part of the imidazole ring is included in the π-conjugated system, Sumire has a longer absorption wavelength than bfVFP. However, the exclusion of the ESPT pathway in Sumire suppresses the red shift in fluorescence, which is probably the reason that the emission wavelength of Sumire is shorter than that of bfVFP.
We demonstrated a method for creating FRET-type indicators for multi-parameter simultaneous observation by using Sumire and T-Sapphire. Since Sumire and T-Sapphire are mutants created from avGFP as with CFP and YFP, it is expected that these mutants have very similar structures to each other.
Since hydration of the chromophore potentially occurs in chromophores by replacing the 66th tyrosine with another aromatic amino acids, the strategy used in this study may be useful for further multi-colorization of fluorescent proteins in the future. It may also be possible to further shorten the wavelength by applying the removal of the ESPT pathway to the aforementioned bfVFP.vector encoding sfGFP was used as the starting material for the development of Sumire cells.
was collected by centrifugation, resuspended in buffer containing 50 mM Tris-HCl and 20 mM imidazole, and crushed using a French press. Samples of the supernatant fraction and pellet were used to confirm that Sumire solubilizes to the same extent as sfGFP by SDS pages . The supernatant of the centrifuged bacterial crushing solution was adsorbed onto Ni-NTA resin in an open column, washed with buffer for resuspension, and eluted with buffer containing 250 mM imidazole.
