Prokaryotic Cell Bank Construction
uBriGene establishes primary cell bank (PCB), the main cell bank (MCB) and the working cell bank (WCB) for plasmid production, and the inspection of the prokaryotic cell bank is completed in accordance with industry standard. Our GMP plant is equipped with dedicated suites for prokaryotic cell bank construction and storage, which enable us to build a three-tiered prokaryotic cell bank that meets regulatory requirements for our clients.
​
The establishment of a highly stable prokaryotic cell bank is crucial for ensuring the consistency of the production process. Our GMP plant is equipped with dedicated suites for prokaryotic cell bank construction and storage, which enable us to provide PCB, MCB and WCB construction and storage services. All GMP prokaryotic cell banks are identified and verified in accordance with the requirements of the industry standard to ensure quality and stability.
