[ 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 ] - Capsule Polysaccharide Synthase 1 (CPS1) Homolog in Aspergillus fumigatus: A Gene Disruption Study

Introduction: Aspergillus fumigatus is the leading cause of invasive aspergillosis in immunocompromised patients with a high rate of mortality. Despite introduction of several classes of antifungal drugs, the limitations of current therapies have prompted an intense research toward the discovery of new antifungal compounds. In a recent study, several potential drug targets were identified based...

[ 4 ] - Targeted Deletion of Los1 Homologue Affects the Production of a Recombinant Model Protein in Pichia pastoris

Background: The methylotrophic yeast Pichia pastoris is an appealing production host for a variety of recombinant, including biologics. In this sense, various genetic- and non-genetic-based techniques have been implemented to improve the production efficiency of this expression platform. Los1 (loss of supression) encodes a non-essential nuclear tRNA exporter in Saccharomyces cerevisiae, which i...
