Gibco PeproTech recombinant growth factors for cell culture

Growth factors are cell signaling proteins that play important roles in cell proliferation, differentiation, and survival. In cell culture, growth factors can be supplied as serum or purified recombinant proteins. High-quality cell culture growth factors support cell health and provide stable and repeatable conditions for in vitro studies of mammalian cells. By optimizing concentrations of growth factors in cell culture, you can drive proliferation or differentiation to a particular phenotype.

Recombinant growth factors provide consistent behavior of cell cultures

Use of recombinant growth factors in mammalian cell culture gives you a higher level of control over experimental conditions, which can lead to more reproducible results in cell-based studies. PeproTech growth factors are high-quality recombinant proteins that offer consistency in quality and supply, reducing the risk of failed cell cultures and lost time.
