[Photochemiluminescence of tryptophan-containing peptides and proteins during photooxidation. VII. Mechanism of sensitization by eosin of the photochemiluminescence of human serum albumin solutions].

Dependence of photochemoluminescence (PCL) intensity of serum albumin solutions with eosine initiated under light illumination with the wave length of 546 nm on oxygen concentration in solution has been studied. The luminescence intensity was shown to increase gradually with the increase of oxygen concentration. The relationship obtained is described by an empyric formula.

[Photochemoluminescence of tryptophan-containing peptides and proteins during photooxidation. VI. Kinetic patterns of eosin sensitized photochemoluminescence of solutions of human serum albumin].

Regulariteis of sensitized photochemoluminescence of serum albumine solutions have been studied. The dependence of luminescence intensity on the dye cancentration is of an extremal character; at low concentrations it is determined by the Lambert--Beer law; at high concentrations quenching processes proceed. The shape of kinetic curves of after-luminescence and rise of luminescence is studied.
