Finding the right CDMO partner for cell line development

Drug Target Review

Together, these attributes provide a strong foundation for protein expression with enough adaptability to produce much of the commercial and therapeutic protein market. They’re prepared for complexity Successful expression of the gene of interest is not sufficient on its own for large-scale production.

Ligustrazine improves the compensative effect of Akt survival signaling to protect liver Kupffer cells in trauma?hemorrhagic shock rats

Chemical Biology and Drug Design

We hypothesized that ligustrazine could protect liver by decreasing the inflammation response, protein production, and apoptosis in THS rats. The protein expressions were detected via western blot. Ligustrazine at doses of 100 and 1000 μg/mL was administrated in Kupffer cells isolated from THS rats.

Key considerations before commencing cell line development

Drug Target Review

A good introduction to the use of CHO cells for biotherapeutics production can be found in an article commemorating the 20th anniversary of the approval of a product produced using CHO cells. 1 Another critical component in this first step is the selectable marker that will be inserted into the genome along with the GOIs.
