Abstract
The present invention provides a method for photoinactivating malignant cells in a cell sample. The method comprises incubating the cell sample with a concentration of Pc 4 effective to cause a substantial number of the malignant cells contained in the cell sample to absorb Pc 4 such that upon application of a sufficient dose of red light, the Pc 4 absorbed malignant cells will be photoinactivated; and applying a sufficient dose of red light to the cell sample to photoinactivate the Pc 4 absorbed malignant cells contained in the cell sample.
