N2 laser-induced oxidation of hemoproteins in red blood cell lysate.
Irradiation of red blood cell lysate with a N(2) laser (337 nm) was observed to induce oxidation of hemoproteins. This process showed a strong dependence on the concentration of red blood cell lysate and the dose of radiation. Studies of mechanisms and experiments with deoxygenated red blood cell lysate rule out involvement of any reactive oxygen species and suggest that the process is not a photodynamic reaction.
