Cell Line Characterization

Cell Bank

Cell line characterization is a key step in ensuring the safety of biopharmaceutical products with the aim of confirming the identity, purity, genetic stability and tumorigenicity of cell lines. This characterization can ensure that the source of the cell line is authentic and free from contamination, undesirable cells and foreign factors such as bacteria, fungi, mycoplasmas, mycobacteria and viruses. International regulatory guidelines such as ICH (Q5A, Q5B, Q5D), EP and USP for cell lines characterization mainly focus on three areas:

1. Source history and generation of cell lines
2. Establish characteristics and tests of cell line identity, purity and genetic stability
3. The banking procedures of the cell line

Creative Biolabs has extensive experience in the cell bank characterization for biopharmaceutical and vaccine production. We offer a wide range of services to characterize cell banks, develop and design scientifically-validated and proven cell line characterization testing methods.
