Master Cell Bank (MCB)

A Master Cell Bank (MCB) is a carefully prepared and well-characterized collection of living cells used to produce medicines, especially biopharmaceuticals. It serves as a reliable, standardized source to generate large quantities of cells needed for manufacturing drugs, ensuring consistency and quality. The MCB is created from a single, healthy cell line, stored under strict conditions to prevent contamination or genetic changes. Before use, tests confirm its safety and stability. Overall, the MCB is fundamental for producing safe, effective biologic medicines in a controlled, repeatable manner.
