Mammalian Cell Culture Protein Expression

Mammalian cell expression has become the dominant recombinant protein production system for clinical applications because of its capacity for post translational modification and human protein like molecular structure assembly.

Mammalian cell culture protein expression.

While expression and production have been fully developed and chinese ham. In last two decades mammalian cell protein expression has become the dominant recombinant protein production system for clinical applications producing more than half of the biopharmaceutical products on the market and several hundreds of candidates in clinical development. This is where mammalian cells can really shine creating more native natural proteins and effective antibodies. Cho cells can grow very well in serum free cell culture medium which eliminates serum as a potential source for infectious agents providing more safety.

This blog focuses on the differences between bacterial and mammalian cell expression systems. Chinese hamster ovary cho cells which have been successfully used for the manufacture of fda approved therapeutic proteins and antibodies are prominent in stable expression stably transfected cho cell line is the most suitable mammalian host for high yield production of recombinant proteins. Therefore the mammalian expression system is suitable for expressing complicated modified functional proteins antibodies. It is designed for high yield transient expression and display of mammalian cell surface membrane proteins including g protein coupled receptors gpcrs in an aqueous soluble format.

Significant progress in developing and. The gibco expi293 membranepro expression system combines the benefits of the expi293 expression system and the gibco membranepro expression system. Cho cells are excellent in protein folding of complex proteins including their posttranslational modification ptm. Cho cells grow mostly in suspension allowing volumetric.

Widely used for the production of recombinant proteins for structural studies insect expression platforms are inexpensive scalable and less demanding than mammalian cells. Why cho cells are frequently used for mammalian protein expression. These cells can be grown in spinner or shaker flasks and do not require a co 2 enriched atmosphere established insect cell lines may produce recombinant proteins with high yields and require smaller culture. In mammalian cell culture.
