[Vitamin B6 fluorescence in cells].

The band of cell fluorescence with the maximum of 395-400 nm is registered. This band is exposed on the phone of the tryptophane by wavelength excitation lambdaex=250-260 nm, and in pure scape by lambdaex=310-326 nm. Pyridoxin - substrate of vitamin B6 has identical parameters of spectra excitation and emission of neutral (pH 7) and acid (pH 2) solutions. After temperature damage of cells the intensity of this band increases.
