HumanKine^® TGF beta 1, Human Recombinant Xeno-Free

HumanKine growth factors are expressed in a proprietary human 293 protein expression system and are manufactured without the use of any animal products and are considered Xeno-Free.

Transforming growth factor beta (TGF-B) is a multifunctional cytokine that controls proliferation, differentiation, and other functions in many cell types. TGF-B acts synergistically with TGF-A in inducing transformation. It also acts as a negative autocrine growth factor. TGF-B regulates the actions of many other growth factors and determines a positive or negative direction of their effects. It plays an important role in bone remodeling. It is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts.
