A U.S. Patent for “Methods for Transduction and Cell Processing” was awarded to Juno Therapeutics on October 1st, 2019. The present invention is a method, system, and kit for cell processing, e.g., for therapeutic use, such as for adoptive cell therapy. The provided methods include transduction methods, in which cells and virus are incubated under conditions that result in transduction of the cells with a viral vector. The incubation in some embodiments is carried out in an internal cavity of a generally rigid centrifugal chamber, such as a cylindrical chamber made of hard plastic, the cavity of which may have a variable volume. Learn More
