Cell line construction.
Methods to generate stable cell lines.
Stable cell line construction for protein antibody production.
The amount of g418 required to kill cells not expressing the construct will vary from cell line to cell line.
To create stable cell lines is a key method in reducing the production costs of biopharmaceuticals.
Limiting dilution is a technique that relies on statistical probability but is time consuming.
Selection antibiotic e g puromycin microcentrifuge tubes.
When large amount of recombinant protein is required stable expression line construction is recommended for reproducible and cost effective protein production.
Depending on the scope of the experiment several options are used for the generation of a stable cell line.
Do not add penicillin streptomycin to the media.
Check the cells for mycoplasma regularly.
The first step in the process is the isolation of single viable cells.
Lenti x 293t cells or alternative cell lines target cell line any human cancer cell line titered lentivirus containing your sequence of interest.
According to the upstream regulator of the reporter gene reporter cell lines can be further divided into two groups.
Infection efficiency will vary between cell lines.
Construction of a stable cell line usually takes 3 steps.
Do not over or under grow your cells.
Cell line development requires the discovery of single cell derived clones that produce high and consistent levels of the target therapeutic protein.
The health of the the target cell line is critical for obtaining accurate results.
We have titrated the amount required for our hela cell lines and this can be a starting point for other cell lines.
Biologics international corp bic owns highly qualified experts and decades of experience in upstream bio pharmaceutical development providing you with stable cell line development services.
A mixed population of drug resistant cells can be used directly for experimental analysis with the advantage of generating fast results but also the disadvantage of dealing with an undefined and.
Delivery of the target gene into the host cell screening of stable expression clones and stability test.
We do this for both gs system cell lines and cell lines brought to us by our customers.
