Impact of Culture Conditions on Recombinant Antibody Yield from Mammalian Cells
The production of recombinant antibodies from mammalian cells is a complex process that can be significantly influenced by culture conditions. Variables such as cell density, media composition, temperature, and pH play crucial roles in determining antibody production levels. Optimizing these parameters is essential for maximizing yield and ensuring the quality of the engineered antibodies produced.
For example, cell density can directly impact antibody production by influencing nutrient availability and waste removal. Media composition, which includes essential nutrients, growth factors, and supplements, provides the necessary building blocks for protein synthesis. Temperature and pH levels must be carefully controlled to ensure cell viability and optimal enzyme activity involved in antibody production.
