[ 1 ] - Effect of Cysteamine on Cell Growth and IgG4 Production in Recombinant Sp2.0 Cells

The manipulation of redox potential in secretory pathway by thiol reducing agents can be a strategy to improve the production levels of disulfide-bonded proteins including recombinant antibodies. Here we have studied the influence of cysteamine on viability and the production level of IgG4 in Sp2.0 cells. For this purpose, the recombinant Sp2.0 cells producing an anti CD33 IgG4, were subjected ...

[ 3 ] - Main Quality Attributes of Monoclonal Antibodies and Effect of Cell Culture Components

The culture media optimization is an inevitable part of upstream process development in therapeutic monoclonal antibodies (mAbs) production. The quality by design (QbD) approach defines the assured quality of the final product through the development stage. An important step in QbD is determination of the main quality attributes. During the media optimization, some of the main quality attribute...

[ 4 ] - Physicochemical Characterization of Altebrel™, a Proposed Etanercept Biosimilar

Background: Etanercept is prescribed for the rapid and effective treatment of chronic immune-mediated inflammatory disorders. Due to the expiration of etanercept patents and worldwide demand for comparable and more affordable substitutes, several biosimilars of etanercept have been approved in different countries and new ones are in the process of approval.Objectives: In the present study...
