Repligen Solutions from Gene to Therapy

Gene Therapy has immense potential to transform the lives of patients with genetic diseases. As demand for plasmids and viral vectors outpace capacity, a greater than 10-fold and potentially close to 100-fold increase in manufacturing efficiency for the gene therapy reagents is likely required to meet a demand curve that is increasing exponentially. Repligen solutions aim to meet the needs for optimized processes, higher yields, and improved process quality - setting new standards for modern scalable processes from gene to therapy.

AAV case study: 3X titer with integrated clarification

AAV case study: 3X titer with integrated clarification

Two case studies illustrate multi-fold upstream AAV titer increases for viral vector from HEK293 cells. In addition to productivity gains, XCell™ and TFDF® technologies clarify conditioned media for manufacturing operational simplicity. Product yield and process economics in the context of the current viral vector supply demand gap will be discussed.

Advanced chromatography system design increases yield and reduces deviations

Advanced chromatography system design increases yield and reduces deviations

The newly designed Artesyn Chromatography Systems from Repligen execute processes with improved yield, reproducibility, and operational simplicity. Over-molded tubing connections eliminate the use of hose barbs and zip ties, which are prone to leaking. Synergistic multi-valve manifolds create a streamlined liquid path without small crevices that typically cause carry-over between buffers. Batch change-overs can be made in under 30 minutes with no tools. The positive impact on process yield and facility output will be discussed.

Configurability, single-use and compliance for with new automated flat sheet TFF up to 500L

Configurability, single-use and compliance for with new automated flat sheet TFF up to 500L

Abstract Driven by the rise in cell and gene therapies, TFF unit operations at scales from 140 mL to 500 L now require the single-use, automation and data integrity capabilities previously reserved for larger scale systems. The newly developed KrosFlo® FS TFF Systems from Repligen provide walk-away automation for multi-step concentration, diafiltration and fed-batch processes with TMP control, closed and single-use flow paths and 21 CFR Part 11 software compliance for processes up to 500 L. Key components to this new system include: a patented automatic back-pressure control valve, a proprietary advanced microprocessor controller that enables plug-and-play hardware connectivity and modern software built upon a secure SQL database. Key technical features and applications supported by flexible configurations of the KrosFlo® FS TFF Systems will be discussed.

Configurability and Compliance for Automated TFF up to 500L

Driven by the rise in cell and gene therapies, TFF unit operations at scales from 10 mL to 500 L now require the single-use, automation and data integrity capabilities previously reserved for larger scale systems. The newly developed KrosFlo® KMPi TFF System from Repligen provides walk-away automation for concentration, diafiltration and fed-batch processes with TMP control, closed and single-use flow paths and 21 CFR Part 11 software compliance for processes up to 500L. Key components to this new system include: a patented automatic back-pressure control valve, a proprietary control board that enables plug-and-play hardware connectivity and modern software built upon a secure SQL database. Key technical features and applications supported by flexible configurations of the KrosFlo® KMPi TFF System will be discussed.

An improved workflow for miniaturized pre-packed columns and automation

An improved workflow for miniaturized pre-packed columns and automation

A workflow for automated chromatography process development created by Repligen, Tecan, and Synthace enables efficient design, deployment, and analysis of downstream purification strategies. Miniaturized OPUS® RoboColumn® Columns reduce resource demand and allow for parallelization of experiments. In conjunction with robotic liquid handling from Tecan and purpose-built automation software from Synthace, RoboColumn® Column users can optimize yield, purity, and reproducibility for expediting downstream development. The synergistic benefits of OPUS® RoboColumn® Columns, Tecan robotics, and Synthace software will be demonstrated in the context of a case study that would be unapproachable using traditional methods.
