DNA concentration in harvest affects retrovirus clearance capabilities of protein A chromatography

open access: yesBiotechnology Progress, EarlyView.
Abstract Protein A chromatography is a key unit operation in biopharmaceutical purification, widely used to capture monoclonal antibodies (mAbs) from harvest cell culture fluid (HCCF). In addition to its primary function, protein A chromatography is also frequently tested for its ability to remove viruses. Although protein A specifically binds mAbs and

Development and application of a mechanistic model for protein A resolution of a bispecific antibody for process characterization and optimization

open access: yesBiotechnology Progress, EarlyView.
Abstract Regeneron's bispecific technology, based on a fully human IgG antibody construct, consists of two distinct heavy chains and a common light chain co‐expressed in a single cell. The co‐expression of the two distinct heavy chains, one of which contains a dipeptide substitution that ablates Protein A binding, leads to the formation of three ...

Flocculation using selected cationic polymers reduces high‐risk host cell proteins in monoclonal antibody processes already during primary recovery

open access: yesBiotechnology Progress, EarlyView.
Flocculation using cationic polymers leads to the creation of large floc complexes. Negative charged species like cells, cell debris, and negatively charged host cell impurities like host cell DNA and host cell proteins are trapped within the complex while the positively charged monoclonal antibody stays in solution.

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

open access: yesCarbon Energy, EarlyView.
A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...
