  • Method and means for purifying retroviral vectors
    Patent number: 10745715
    Abstract: The present invention relates to a producer cell which expresses a tagging protein at the cell surface, such that retroviral vectors produced by the cell are tagged with the tagging protein, wherein the tagging protein comprises: i) a binding domain which binds to a capture moiety ii) a spacer; and iii) a membrane targeting domain such that, when incorporated a retroviral vector, the tagging protein facilitates purification of the retroviral vector from cellular supernatant via binding of the tagging protein to the capture moiety. The present invention also relates to a retroviral vector comprising such a producer cell-derived tagging protein.
    Type: Grant
