The present invention provides methods of detecting and/or characterizing the viral vector particle content of a medium. A medium is provided and contacted with an excitation energy such that, if a viral vector particle is in the medium, an electron associated with the intrinsically fluorogenic portion of the viral vector particle will be raised to an excited energy state. The excited electron is permitted to emit radiation having an emission wavelength which is detected. The viral vector particle content of the medium then can be evaluated by comparing the detected emission wavelength with a standard signal. For example, the number of viral vector particles in a medium can be quantified by comparing the detected wavelength and its corresponding intensity to a standard signal. Similar methods for evaluating the adenoviral vector particle content of a medium and the intrinsically fluorogenic adenoviral structural protein content of a medium are provided.
