Cell Line Expansion Service & Cell Banking Service

The preparation of cells derived from a continuously growing culture for use in an assay is a challenging and time-consuming process. It is essential to ensure that the cells are prepared in a timely manner, in the correct quantities and of a consistent quality. trenzyme’s cell culture department is specialized in the expansion and cryopreservation of assay ready cells for pharmaceutical and biotechnology companies. trenzyme‘s assay-ready frozen cells are optimized to perform in your functional assay and provided in suitable aliquots according to your needs. Thus, the cells batches enable streamlining of experimental workflows for any kind of assay such as toxicology assessment, and pharmacological high throughput screening campaigns.

Cell Line Expansion Service

Streamline Your Experimental Workflow With Assay-Ready Frozen Cells

In order to obtain consistent and reliable results from toxicology assessments, bioassays and high-throughput screening campaigns, it is essential to work with cells that have been sourced from a quality-controlled cell bank.

trenzyme‘s cell line expansion service enables a convenient workflow by decoupling cell culture and assay procedure. The assay-ready frozen cells are cryopreserved in a single batch at high viability, thus allowing for the convenient use of these cells at any time. This process simplifies the overall assay performance. A quality-controlled cell bank of suitable aliquots will be cryopreserved according to your requirements, either as a small research cell bank (RCB) or as a larger, for research-use-only, two-tier (two-stage) cell bank, consisting of a master cell bank (MCB) and a working cell bank (WCB).

Our cell expansion and cell banking service offers the expansion of assay-ready cells, as well as the option of using your research cell line of choice, including stem cells and stem cell-derived cell types (take a look at our stem cell differentiation and stem cell characterization services).
