A deep dive into optimizing AAV capture and polishing to maximize both yield and purity
It’s critical to maximize both overall yield and removal of impurities, including empty capsids.
To meet these needs, Cytiva developed scalable capture and polishing chromatography steps for recom…
Article
As the therapeutic pipeline diversifies, chromatography toolboxes are expanding.
Depending on the structure of the target antibody and the impurity profile, other affinities, like protein L or variants of protein A, may improve purity and increase removal of impurities.
