Recent Advances in High Cell Density Cultivation for Production of Recombinant Protein

This paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. High cell density cultures offer an efficient means for the economical production of recombinant proteins. However, there are still some challenges associated with high cell density cultivation (HCDC) techniques. A variety of strategies in several aspects including host design...

Recent advances in recombinant protein production

Designing appropriate expression vectors is one of the critical steps in the generation of stable cell lines for recombinant protein production. Conventional expression vectors are severely affected by the chromatin environment surrounding their integration site into the host genome, resulting in low expression levels and transgene silencing. In the past, a new generation of expression vectors ...

Optimization of secretory expression of recombinant hGM-CSF in high cell density cultivation of recombinant Escherichia coli using Taguchi statistical method

Human granulocyte macrophage colony stimulating factor (hGM-CSF) has many therapeutic applications.In this study, in order to verify the purification process, the effect of carbon source, IPTG concentration andpost-induction time on the secretion of recombinant hGM-CSF into the culture medium by recombinantEscherichia coli during high cell density cultivation were evaluated by...

High cell density cultivation and recombinant protein production with Escherichia coli in a rocking-motion-type bioreactor

BACKGROUND Single-use rocking-motion-type bag bioreactors provide advantages compared to standard stirred tank bioreactors by decreased contamination risks, reduction of cleaning and sterilization time, lower investment costs, and simple and cheaper validation. Currently, they are widely used for cell cultures although their use for small and medium scale production of recombinant proteins with...
