Abstract
A method for treating a body fluid to at least substantially inactivate viral contaminants that may be present therein is provided. The method includes the steps of: providing a body fluid; adding to the body fluid a viral inactivating agent to create a resultant product; and passing the resultant product through a column including material having an affinity for the viral inactivating agent.
Claims1
A method for treating a body fluid to at least substantially inactivate viral contaminants that may be present therein comprising the steps of:
- providing a therapeutically useful body fluid;
- adding to the body fluid a viral inactivation agent selected from the group consisting of porphyrin, psoralen, phthalocyanine, and hypericin in an amount and under conditions effective to at least substantially inactivate any viral contaminants present in the body fluid without destroying the therapeutic benefits of the body fluid;
- and
- passing the resultant product through a column including macroporous polymeric beads having an affinity for the viral inactivation agent and photoproducts generated by irradiating the viral inactivation agent with the light to remove all measurable viral inactivation agent and photoproducts, as determined by high pressure liquid chromatography, from the resultant product without destroying the therapeutic benefits of the body fluid to provide a treated body fluid suitable for administration to a patient.
