Method And System Of Protein Extraction

Patent No. EP3794013 (titled "Method And System Of Protein Extraction") was filed by CSL Behring on May 17, 2019. The application was issued on Feb 21, 2024.

Patent Summary

A method for extracting proteins from precipitates, particularly recombinant and/or plasma-derived proteins including immunoglobulins, using a continuous filtration process with high dilution factors to achieve improved yield and purity. The method involves feeding a protein-containing precipitate suspension into a first filtration unit, where it is continuously diluted to a predetermined dilution factor, and then subjecting the resulting permeate to a second filtration step to concentrate the protein of interest. The process can be repeated until the desired protein concentration is achieved, and is particularly suited for industrial-scale production of therapeutic proteins.
