Triplet state of protoporphyrin IX
Journal of the Chemical Society, Chemical Communications, 1978Flash photolysis of aqueous solutions of protoporphyrin IX at pH values below 2 results in strong triplet state absorptions while at any higher pH, including physiologically relevant values, no triplet state formation can be detected.

Applied Spectroscopy, 2008
Derivative variable-angle synchronous fluorescence (DVASF) spectrometry improves the spectral resolution and selectivity of the fluorescence method. The feasibility of DVASF spectrometry for the simultaneous determination of protoporphyrin IX (PP) and zinc protoporphyrin IX (ZnPP) was investigated.

AbstractQuantification of erythrocyte zinc protoporphyrin IX (ZnPP) and protoporphyrin IX (PPIX), individually or jointly, is useful for the diagnostic evaluation of iron deficiency, iron‐restricted erythropoiesis, lead exposure, and porphyrias. A method for simultaneous quantification of ZnPP and PPIX in unwashed blood samples is described, using dual‐

Photosensitization of retinal pigment epithelium by protoporphyrin IX
Graefe's Archive for Clinical and Experimental Ophthalmology, 1998Clinical evidence of injury to the retinal pigment epithelium is an important feature of age-related macular degeneration, but the mechanism of this injury is unknown. Blue-light-dependent activation of the blood-borne photosensitizer protoporphyrin IX is known to produce free radicals which may damage cells and tissues.
