Introduction: Transforming growth factor beta 1 or TGF-beta1 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. TGF-beta1 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-beta1 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-beta1. Some T cells (e.g. regulatory T cells) release TGF-beta1 to inhibit the actions of other T cells. Interleukin 1- and interleukin 2-dependent proliferation of activated T cells, and the activation of quiescent helper T cells and cytotoxic T cells is prevented by the activity of TGF-beta1. Similarly, TGF-beta1 can inhibit the secretion and activity of many other cytokines including interferon-gamma, tumor necrosis factor-alpha (TNF-alpha) and various interleukins. It can also decrease the expression levels of cytokine receptors, such as the IL-2 receptor to down-regulate the activity of immune cells. However, TGF-beta1 can also increase the expression of certain cytokines in T cells and promote their proliferation, particularly if the cells are immature. TGF-beta1 has similar effects on B cells that also vary according to the differentiation state of the cell. It inhibits proliferation and apoptosis of B cells, and plays a role in controlling the expression of antibody, transferrin and MHC class II proteins on immature and mature B cells. The effects of TGF-beta1 on macrophages and monocytes are predominantly suppressive; this cytokine can inhibit the proliferation of these cells and prevent their production of reactive oxygen and nitrogen intermediates. However, as with other cell types, TGF-beta1 can also have the opposite effect on cells of myeloid origin. For example, TGF-beta1 acts as a chemoattractant, directing an immune response to some pathogens; macrophages and monocytes respond to low levels of TGF-beta1 in a chemotactic manner. Furthermore, the expression of monocytic cytokines and phagocytic killing by macrophages can be increased by the action of TGF-beta1.

Principle of the Assay: The microtiter plate provided in this kit has been pre-coated with goat-anti-rabbit antibody. Standards or samples are added to the appropriate microtiter plate wells with an antibody specific for TGF-beta1 and Horseradish Peroxidase (HRP) conjugated TGF-beta1, and incubated. A competitive inhibition reaction is launched between TGF-beta1 (Standards or samples) and Horseradish Peroxidase (HRP) conjugated TGF-beta1 with the antibody specific for TGF-beta1. Then substrate solutions are added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The concentration of TGF-beta1 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Uniprot Description

Function: Multifunctional protein that controls proliferation, differentiation and other functions in many cell types. Many cells synthesize TGFB1 and have specific receptors for it. It positively and negatively regulates many other growth factors. It plays an important role in bone remodeling as it is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts
