Starting with a cell line
The choice of cell line is crucial when expressing a recombinant protein. Several factors affecting yield, functionality and overall quality of the recombinant protein are considered in the selection process. While the target protein to be manufactured is a main driver (ex. need for post-translational modification, protein folding and stability, protein solubility) also regulatory and economical aspects (expression level, cost and time, scalability of the process) should be evaluated.
Eurofins CDMO works with different expression systems like E.coli, yeast cell lines, as well as mammalian cell lines (CHO, HEK293, hybridoma).
Microbial cell line development
We onboard your microbial manufacturing project from the early beginnings. Our microbial cell line development services entail:
- Host strain selection, vector design and construction
- Screening of clones for soluble and insoluble (inclusion body) cytosolic expression in E.coli
- Screening of clones for periplasmic secretion in E.coli
- Screening of clones for expression of secreted protein in yeast (Pichia pastoris, Saccharomyces, Hansenula)
- Cell banking services from development (RCB) to GMP (MCB/WCB)
- Stability studies
- Documented cell line generation for easy transfer to GMP (cell line history file and quality reports)
For mammalian cell line development we can tap into the expertise of the Eurofins network or carefully selected partners.
