MDCK Cell Bank Characterization

The MDCK cell line was established from the kidney of a healthy cocker spaniel dog in 1958 and has a long history in the studies of influenza viruses. The conventional MDCK cell with adherent growth (MDCK-A) is a good candidate for the preparation of vaccine seed viruses, since it supports efficient growth of human influenza viruses. The most significant utilization area of MDCK cells is industrial vaccine production and studies of viral infections.

Creative Bioarray has extensive experience in characterization of cGMP MDCK cell banks used in production of biologic drugs. Our MDCK cell line characterization allows you to efficiently streamline your cGMP-compliant manufacturing processes and accelerate toward successful commercialization. And our reporting fulfils FDA and EMA regulatory requirements for pharmaceuticals for human use (ICH guidelines Q5B and Q5D, CTD Quality module, section 3.2.S.2.3).

Cell Line Scope

According to document ICH Q5D 'Quality of Biological Products: Derivatives and Characterization of Cellular Substrates for the Production of Biotechnology/Biological Products', Creative Bioarray performs MDCK cell bank characterization on the following cell lines:

  • Research Cell Bank (RCB)
  • Working Cell Bank (WCB)
  • Master Cell Bank (MCB)
  • End-of-Production Cells (EOPC)

Cell Bank characterization is an essential step in ensuring the safety of biopharmaceutical products with the aim of confirming the identity, purity and genetic stability of cell lines. This characterization can ensure that the cell banks are free of contaminants and are able to provide a solid, stable foundation to continue production process years down the road. International regulatory guidelines such as ICH (Q5A, Q5B, Q5D), EP and USP for cell lines characterization mainly focus on four areas:

  • The origin and history of the cell line cellular morphology and growth characteristics
  • Purity of the cell lines (i.e., absence of contaminating cells, microbial contaminations, and contaminations by adventitious viruses)
  • Tumorigenicity and oncogenicity
  • Genetic Stability
