Hematoporphyrin (dihydrochloride)

Hematoporphyrin dihydrochloride (Hematoporphyrin IX dihydrochloride), a photosensitizer, is a substrate for affinity chromatography of heme-binding proteins. Hematoporphyrin dihydrochloride can induce apoptosis in U87 glioma cells and decrease tumor growth in vivo when exposed to red light[1][2][3].
