Descrição

Free base porphyrin (PPhe), derivatized with aminosulfonyl groups linked to the aromatic amino acid phenylalanine at the meso-positions, was mixed with DMPC vesicles. The resulting interaction was studied by absorption, steady-state and transient state fluorescence, at different pHs. http://www.sciencedirect.com/science/article/B6TFB-4R68NKV-2/1/aca6e255f297903981898ccea264a386
