Welcome and Introduction

09:30 AM PDT

High Cell Density perfusion for the production of AAV2 viral vector using the Repligen XCell™ ATF System

09:45 AM PDT

Christa Short, Associate Director, Upstream Mammalian Bioprocess, Cytovance Biologics


An initial case study examining the effects of pre-transfection perfusion on AAV2 viral vector production rates will be presented. Initial studies indicate the exchange of vital nutrients prior to transfection maintain cells in a more optimal state of exponential growth during transfection, which leads to higher viral production.

Technology breakthrough: Closed, Gamma-irradiated flat sheet cassettes for bioburden-sensitive TFF processes

10:15 AM PDT

Monica Amin, Field Application Scientist, Repligen


In response to customers challenged with bioburden-sensitive TFF processes, technology leading single-use TangenX™ TFF Flat Sheet Cassettes are now available in closed and irradiated format. Used in ultrafiltration and diafiltration, the new cassettes come pre-assembled and pre-tested, using the same proprietary membrane choices and multiple MWCOs as SIUS™ Flat Sheet Cassettes. This session will demonstrate how the new cassettes integrate easily into any process with faster turnaround time, improved productivity and lower risk of contamination.

High Productivity Harvest - Intensify harvest and displace clarification in Fed Batch cell culture

11:30 AM PDT

John Bonham-Carter, Product Line Leader, Cell Culture and Clarification Business, Repligen


High Productivity Harvest (HPH) is a novel application developed by Repligen that enables you to harvest a fed batch bioreactor in a fully sterile manner while eliminating both centrifugation and depth filtration. A 0.2 µm filtered, closed system and single step process using the XCell™ ATF System, HPH can significantly increase yields above industry standards and generate a sterile clarified batch harvest ready for either batch or continuous chromatography. This presentation will demonstrate how HPH works, present initial results of up to a 2-fold increase in protein production, and how you can apply HPH specific to your product need or facility design.

Speaker Bio

John Bonham-Carter joined Repligen in 2014 as part of the acquisition of Refine Technology where he was Vice President. He has developed and worked with different upstream technologies and, most recently, has propelled the XCell™ ATF System to become the dominant industry technology in continuous culture. Previously, he has founded or co-founded multiple companies in several countries in industries from newspapers to bioprocessing. John advises and speaks on small business coaching and entrepreneurship. John is a regular international speaker on bioprocessing. He is the editor of two editions of a book introducing Continuous Bioprocessing.

Lunch and Networking

12:30 PM PDT

Novel single-use, high capacity and flux Tangential Flow Depth Filter (TFDF™) for mAb batch harvest

01:30 PM PDT

Edward Chan, Technical Specialist III, Cell Culture Pilot Plant, Genentech, Inc.


The 2000 L Single-Use Team needs a fully closed and single-use harvest solution for 500 L - 2000 L volumes for the new end-to-end single-use Clinical Supply Center build-out in Genentech South San Francisco to enable cost effective, flexible, faster technology transfer to different sites, and faster biopharmaceutical manufacturing. Traditional batch harvest historically has been performed with centrifugation and/or depth filtration to remove cell mass and further particle removal. Towards a fully closed and single-use harvest process method, the team collaborated with the vendor to develop Tangential Flow Depth Filtration (TFDF™), which was at its Beta testing stage in the first quarter of 2018. The effort focused on understanding the technology and establishing optimal filter properties for harvesting different molecules. Three different filtration scales were assessed. CCF and permeate were analyzed for titer, yield, turbidity, lysis, product quality and impurities at the conclusion of each run. Identification of key filter properties, challenges encountered during evaluation, harvest performance data, and implementation plan will be discussed.
