Purpurins and benzochlorins are hydrophobic second generation photosensitizers, which have sizable absorption in the 650-780 nm range and exhibit photodynamic activity against tumors after visible light treatment. This review summarizes the published data regarding these compounds: from the spectroscopic, photophysical

A minigene encoding rat retinol-binding protein (RBP) was transfected into HeLa cells, which do not express endogenous RBP, transthyretin, or cellular retinol-binding protein. The HeLa cells manufactured and secreted the transfected gene product, demonstrating that RBP-transthyretin assembly is not a
