A Turnkey, Flow-Through-Mode Purification Process to Improve Quality and Safety of Plasma IgG


Plasma-derived immunoglobulins (IgG) are essential medicines that are in worldwide shortage. How to develop optimized processing steps for robust and efficient manufacturing has been a constant goal, to make the most out of the precious plasma raw material. In this study, we present a worse-case equivalent of plasma intermediate, and explore various process steps along the fractionation flow, including flow-through-mode chromatography, affinity chromatography, virus inactivation steps and removal of solvent/detergent, single-pass TFF (SPTFF), clarification, and aseptic filtration, to establish a robust, easy-to-operate, readily scalable plasma IgG process with over 99% purity, depletion of IgA, isoagglutinin, and thrombogenic markers, meeting the commonly required 20% concentration for subcutaneous IgG infusion. Such solutions would be appropriate for various IgG intermediates which help to improve the global supply of immunoglobulins.

In this webinar, you will learn:

  • Intensified plasma Immunoglobulin purifications
  • Scalable process development with the latest technologies
  • Improved safety and quality of plasma IgG meeting required quality attributes
