Cell Line Adaption Service
Full Service to Adapt Your Cells to Serum-Free Conditions
For decades, standard cell culture has been performed in the presence of fetal bovine serum (FBS), which contains growth factors required for cell growth. Basically, FBS is a by-product of cattle farming (meat industry) and its quality depends strongly on the health of the animals and their conditions during this process (general health, nutrition, stress, etc.). Apart from the ethical issues of avoiding the use of animals in science and industry, this fact massively increases the variability of cultures supplemented with FBS, presents a reproducibility problem and is one of the reasons for the reproducibility crisis in science.
Our cell culture experts offer a complete service to adapt your cells to serum-free conditions by our cell line adaptation service. Depending on your requirements, we can adapt your cells to xeno-free, chemically defined (CD) or animal derived component free (ADCF) media. We also offer adaptation as a GMP-compliant service (GMP Services) and provide you with a cell bank by our cell expansion service. In addition, these cells can be used directly in our cell-based assay service in which we use your adapted cells and perfom your assay in-house and the resulting data will be provided to you ( ➥cell-based assay service). You will receive full information on the supplements and their concentrations together with a comprehensive data sheet for your new cell line.

Process of
Cell Line Adaption Service
Feasibility Check & Project Consultion
The feasibility study involves a close dialogue between the customer and our cell culture experts. The customer's requirements are discussed and finally our cell culture experts will suggest you one or more reasonable medium compositions.
Once the customized quotation has been prepared by our team and accepted by the customer, the project can begin.
QC of Incoming Cell Line
During this step of the project we will confirm the culture conditions of the external cell line including mycoplasma test. This step is not necessary when a trenzyme in-house cell line will be used for the project.
- Thawing and cultivation of cells
- Thaw-viability assay, microscopic evaluation and mycoplasma test
- Verification of culture conditions
- Cryopreservation of a small cell bank
Cell Line Adaption
Depending on the cell line that should be adapted it can be beneficial to perform a stepwise adaption or to perform a so-called “do-or-die”-approach.
During adaption the growth of your cell line will be monitored and documented. You will receive full documentation and medium composition in a comprehensive data sheet or optionally a final report. Viability and growth rates will be monitored and documented over several passages for both approaches
- Step-Wise Adaption: The old medium will be replaced slowly in several steps (e.g. 25%, 50%, 75%, 100%)
- „Do-or-Die“-Approach: The old medium will be replaced in one step at once
Cell Line Expansion & Cryopreservation
The adapted cells will be maintained in culture for a few passages in order to validate successful adaption to the new medium. After validation we will expand the cells and cryopreserve them according to your needs (freezing media, number of cells / vial, number of vials).
- Expansion of adapted cell line
- Cryopreservation of a cell bank
Quality Control of the Adapted Cell Line
We thaw your newly adapted cryopreserved cell line to scrutinise viability of the cell line. In order to verify the culture conditions we will passage the cells for another three times.
Standard Quality Control:
- Thaw-Viability Assay
- Mycoplasma Test for your security
Further Optional Analysis Methods According to Your Needs:
- Flow Cytometry ( i.e. expression of specific proteins/genes)
- Immunflourescence
- PCR
- Western Blot
- ELISA
- RT-qPCR

Deliverables
Together with your cryopreserved cells you will obtain comprehensive documentation including
- Data sheet with exact culture conditions and media compositions
- Growth rate documentation
- Optional: a full report about the whole adaption process
Timeline
- The timeline very much depends on the cell line, the doubling rate of the cells and on the type of medium (low or high nutrient content) to which the cells shall be adapted. Therefore timeline ranges from 6 to 12 weeks.
