"The need for better single-use and disposable systems in downstream processing is growing…The move toward disposable upstream bioprocessing will push downstream operations toward innovative alternatives that may include membrane adsorbers and prepacked single-use chromatography columns."
"Disposable Chromatography: Options Are Increasing" Genetic Engineering News, Dec. 10, 2013
CHRETO TechnologyTM process overview illustrating the catch, clean and collect steps. See details below (How does it work?).
The characteristics of the DAP molecule include 1) easy elution and no leakage, 2) specific binding to product (to secure selective reaction with target protein(s) and easy dissolving of formed DAP-target complexes and 3) tight binding to solid support (to secure immobilization and final removal of DAP molecules from product stream)
The purification process consists of three steps: catch, clean and collect.
The left-hand figure (above) shows the chromatogram profile, with two major protein peaks representing the fractions containing the flow through after reaction with DAP (Fraction 7 and Lane 7 on the SDS gel, right panel above), and the fraction containing the purified mAb (Fraction 8 and Lane 8 on the SDS gel above). Lane 3 shows purified DAP; Lane 4 shows the feedstock used and Lane 6 show the same sample run without addition of DAP. Lanes 1 and 10 include the MW marker.
The left-hand figure (above) shows the chromatogram profile, with three major protein peaks representing, from left to right: proteins not bound to DAP, proteins washed away from DAP-target complexes and the elution of the DAP-purified IVIG, respectively. Arrows indicate the fractions that are further analysed by SDS-PAGE (figure on the right). Lanes 7-9 on the SDS-PAGE contain highly purified gamma globulins (right-hand panel above).
High purity was obtained using a single purification step for both mAb purification and plasma fractionation.
