At the core of cutting-edge research and biopharmaceutical production lies the crucial need to preserve and store precious cell lines, ensuring their availability for future studies and therapeutic applications. Cell banking plays a critical role in science and medicine by preserving and storing valuable cell lines. This essential process is instrumental in advancing research and biopharmaceutical production.

In this article, we will explore the purpose and applications of cell banking, examining its significance in scientific discoveries and medical breakthroughs.

Cell banking in brief

Cell banking is a fundamental process in the production of biopharmaceuticals, involving the methodical preservation and storage of cell lines. These cell lines consist of specific types of cells that have been isolated, characterized, and cultivated for research or therapeutic purposes. The primary objective of cell banking is to ensure a stable and consistent cell source for various applications.

What is the purpose of cell banking?

Cell banking serves several crucial purposes that are integral to the progress of scientific research and biopharmaceutical applications. Let's take a closer look at the key objectives and benefits of cell banking:

1. Ensuring a stable and consistent cell source

One of the primary purposes of cell banking is to establish a stable and consistent source of cells for research and production. Cell lines used in scientific studies are susceptible to changes over time due to genetic drift, environmental factors, or other variables.

By creating a cell bank, researchers can freeze and store cells at a specific passage level, preserving their characteristics and minimizing variations between experiments. This consistency enhances the reproducibility of results, which is a critical aspect of scientific validity.

2. Facilitating reproducibility of experimental results

Reproducibility is a cornerstone of the scientific method, ensuring that experiments can be independently verified and validated. Cell banking plays a vital role in promoting reproducibility by providing researchers with a standardized and well-characterized cell source. By using the same cell line from a cell bank across different experiments and laboratories, scientists can confidently compare results, validate hypotheses, and build upon previous findings.

3. Serving as a backup and contingency plan

Cell lines are delicate and susceptible to contamination, genetic mutations, or accidental loss. Such events can be devastating for ongoing research or biopharmaceutical production.

Cell banking serves as an essential contingency plan, allowing researchers to restart experiments or bioproduction processes using frozen cells from the bank. This safeguard ensures that valuable research is not irreversibly compromised and enables the seamless continuation of scientific endeavors.

4. Supporting long-term studies and replication

Many scientific studies require long-term observation and validation through replication. Cell banking provides a means to store cells for extended periods, allowing researchers to conduct follow-up studies and replicate their findings over time. The ability to use the same cell line across multiple experiments, even after months or years, is invaluable for longitudinal studies and longitudinal assessments of drug efficacy or safety.

5. Facilitating collaboration and standardization

Cell banks enable researchers worldwide to work with standardized cell lines, fostering collaboration and knowledge exchange. Commonly used cell lines, such as CHO cells or HEK293 cells,  can be shared among research institutions, promoting consistency and standardization in experimental protocols. This collaborative approach accelerates scientific progress, as scientists can build upon each other's work more efficiently. 

6. Accelerating biopharmaceutical production: Seed Train Intensification

In biopharmaceutical production, the seed train is a critical process involving multiple stages of cell growth to increase cell biomass before entering the production bioreactor. Cell banking plays a vital role in optimizing this seed train intensification process.

By providing a well-characterized and controlled cell source, cell banking reduces the variability and risk associated with using early passages of cells in the seed train. This enables a more efficient and reliable bioproduction process, ultimately speeding up the production of biopharmaceuticals.

Single Use Support has developed solutions to accelerate the conventional seed train process. The intensified process is based on cell bank multiplication - in which the cells are filled into numerous small single-use bags which will be frozen. The seamlessly integrated homogenization solution RoSS.PADL ensures that the cells are evenly distributed into the individual single-use bags. Freezing can be done either down to -80°C / -112°F with the plate-based laboratory freezer or down to -170°C/-274°F with the cryogenic controlled rate freezer.  After thawing, each bag forms the basis for production in the bioreactor.

Banking the Intensified Seed Train

Cell Banking in Seed Train Intensification is a crucial process step in upstream bioprocessing for biopharmaceutical production. Cells that can be cultured into large aliquots, e.g. with cell suspensions, can greatly optimize the cell culture intensification process.
