Abstract
Provided are compositions containing a conjugate containing a phthalocyanine dye, including compositions containing stabilizing agents, such as non-ionic surfactants and/or protectants. In some aspects, the compositions result reduced aggregation of the conjugate due to agitation, temperature exposure, and/or pH. Also provided are articles of manufacture containing the compositions containing the conjugates, and methods for their administration to subjects for photoimmunotherapy. In some embodiments, the phthalocyanine dye conjugates are conjugated to a targeting molecule, such as an antibody, that targets the conjugate to a cell or pathogen, such as by binding to a cell surface protein.
