Patent number: 11104874Abstract: Embodiments provide for introducing a first fluid into a bioreactor and while introducing the first fluid into the bioreactor, circulating a second fluid with a reagent at a first flow rate through the bioreactor. The bioreactor may be maintained in a first orientation for a first period of time to allow at least a first portion of the reagent to coat the bioreactor. The second fluid may then be circulated at a second flow rate slower than the first flow rate to allow a second portion of the reagent to coat the bioreactor. Introduction of the first fluid may promote coating of the bioreactor by ultrafiltration. The introduction of the first fluid may be stopped. A third fluid may be circulated through the bioreactor to remove a portion of the reagent not coated on the bioreactor.Type: GrantFiled: June 7, 2017Date of Patent: August 31, 2021Assignee: Terumo BCT, Inc.Inventors: Nathan D.
