Photodynamic inactivation of viruses in cell-containing compositions. |
摘要 |
<p>The present invention concerns the product produced by inactivating extracellular lipid enveloped pathogenic virus or intracellular pathogenic virus in a composition containing >1 X 10<9> cells/ml and said virus without incurring substantial disruption or inactivation of such cells, the inactivation process comprising contacting the composition with a virucidally effective amount of at least one photoreactive compound having an absorption maximum of >/= 630 nm, light and an oxidizer, thereby substantially to inactivate the virus with retention of cell functionality, greater than 80%. The present invention also concerns the product produced by inactivating virus in a biological composition without incurring substantial disruption or inactivation thereof, the inactivation process comprising contacting said composition with a virucidally effective amount of at least one photoreactive compound, light, and a quencher thereby to inactivate said virus while retaining functionality of said substance. <IMAGE></p> |
