Medchemexpress LLC Protoporphyrin IX | 553-12-8 | MFCD00151109 | 98.0% | 100 MG
Protoporphyrin IX is an endogenous metabolite and a final intermediate in the heme biosynthetic pathway. It functions as a radiation sensitizer, enhancing ROS generation even in hypoxic conditions and inducing DNA damage. It also acts as a photosensitizer that undergoes photobleaching from light irradiation. It accumulates in tumor cells after administration of 5-aminolevulinic acid (5-ALA).

Enzo Life Sciences Protoporphyrin IX (free acid) (1g). CAS: 553-12-8
Protoporphyrin IX free acid, as distinct from its zinc salt (which inhibits heme oxygenase), activates soluble guanylyl cyclase (sGC) by binding directly to the enzyme. A useful reagent in cases where the use of nitric oxide (NO) or nitric oxide donors is undesirable. Alternative name: 8,13-Divinyl-3,7,12,17-tetramethyl-21H,23H-porphine-2,18-dipropionic acid. Purity: ≥95% (HPLC). Appearance: Purple to dark brown solid. Solubility: Dissolve initially in 0.1M base (Tris base or NaOH), then add water miscible organic solvent (EtOH (10mg/ml), MeOH, DMSO (10mg/ml), DMF) until solution is 50/50 base/solvent. When a clear solution is obtained, it can be diluted into an aqueous medium and titrated or buffered to any pH>7. Use immediately. Long Term Storage: -20°C.
