The relevance of the oxygen transfer rate for successful cell cultivation
In the development and manufacture of advanced biopharmaceuticals—including cell and gene therapies—cell expansion is a critical step that directly influences yield, quality, and consistency of the final product. Maintaining a viable and productive cell population requires precise control over multiple parameters within the bioreactor environment. Among these, dissolved oxygen (DO) concentration in the liquid phase stands out as a critical process parameter (CPP).
