Cell Banking

Home / Proteins / Cell Banking

We are fully capable to produce and characterize Master Cell Banks (MCB) and Working Cell Banks (WCB)

In our GMP compliant suits we operate under an appropriate quality system for MCB and WCB manufacturing, characterization and release according to the ICH guidelines. Our team works with you through all stages of cell bank manufacturing, from the initial inquiry, design, and initiation of your project to the production, characterization, storage, and stability testing.

We have generated and characterized microbial and mammalian cell banks for our clients all around the world
