Impact of Culture Conditions on Recombinant Antibody Yield from Mammalian Cells
The yield of recombinant antibodies from mammalian cells is a complex process that can be significantly influenced by culture conditions. Variables such as cell density, media here composition, temperature, and pH play crucial roles in determining antibody production levels. Optimizing these factors is essential for maximizing yield and ensuring the potency of the synthetic 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 additives, provides the necessary building blocks for protein synthesis. Temperature and pH levels must be carefully maintained to ensure cell viability and optimal enzyme activity involved in antibody production.
