Amongst mutants with a disulfide bridge, P451C-V469C and L306C-L309C mutants exhibit a single peak in the red region of the spectrum at pH 7.8. It is worthwhile to note that with the design of a secreted luciferase, the increased optimum temperature, thermostability and emission of red ...

In the single-particle scattering cross-section near backscattering, short-wavelength resonances arise from cavity-like modes to introduce an additional peak in the blue part of the spectrum, compromising the red color. In contrast, these single-particle scattering resonances do not affect our ...

with 3 to 15 moles of ethylene oxide, such as 3-7 or 5-9 moles of ethylene oxide, e.g., 5 or 7 moles thereof. In place of the higher fatty alcohol one may use an alkylphenol, such as one of 8 to 10 carbon atoms in a linear alkyl, e.g., nonylphenol, and the phenol may ...
Z1 represents an aromatic carbon ring nucleus or heterocyclic nucleus composed of 5 to 7 atoms; said nucleus having (a) a nitrogen atom, or (b) a carbon atom bonded to a chelating group at the position adjacent to the position bonded to the azo group; Z3 represents an electron attractive...
