摘要: The present invention pertains to methods of using arginine to inactivate or reduce the infectious titer of enveloped viruses potentially present in biological compositions produced by eukaryotic cells (such as a antibodies or other therapeutic proteins). In some embodiments, inactivation or reduction of viral titers by exposure to arginine is achieved in a neutral (pH ˜7) or near neutral (˜pH 6 to ˜pH 8) environment.
