Thermostable bFGF is a heat-resistant fibroblast growth factor (bFGF) that can be used to stimulate and maintain cell growth in culture. It is an important factor in cell culture and is used to maintain cell viability, health, and proliferative capacity. Conditioned media is a form of cell culture media that has been exposed to cells and contains cell-derived factors such as proteins and hormones. It is commonly used to promote cell health and growth, and can be used in place of fresh media in cell culture processes. Conditioned media can be used to supplement the culture with additional factors such as growth factors and hormones, or to replace certain components such as serum or antibiotics.
