Human Transforming Growth Factor Beta 1 TGFb1 ELISA kit

Transforming growth factor beta 1 or TGF- 1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation, and apoptosis. In humans, TGF- 1 is encoded by the TGFB1 gene. TGF- is a multifunctional set of peptides that controls proliferation, differentiation, and other functions in many cell types. TGF- acts synergistically with transforming growth factor-alpha (TGF- ) in inducing transformation. It also acts as a negative autocrine growth factor. Dysregulation of TGF- activation and signaling may result in apoptosis. Many cells synthesize TGF- and almost all of them have specific receptors for this peptide. TGF- 1, TGF- 2, and TGF- 3 all function through the same receptor signaling systems.TGF- 1 was first identified in human platelets as a protein with a molecular mass of 25 kilodaltons with a potential role in wound healing. It was later characterized as a large protein precursor (containing 390 amino acids) that was proteolytically processed to produce a mature peptide of 112 amino acids. TGF- 1 plays an important role in controlling the immune system, and shows different activities on different types of cell, or cells at different developmental stages. Most immune cells (or leukocytes) secrete TGF- 1
