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: This assay employs the competitive inhibition enzyme immunoassay technique. A antibody specific to TGF-beta1 has been pre-coated onto a microplate. Standards or samples are added to the appropriate microtiter plate wells with biotin-conjugated TGF-beta1 and incubated. A competitive inhibition reaction is launched between TGF-beta1 (Standards or samples) and Biotin-conjugated TGF-beta1 with the pre-coated antibody specific for TGF-beta1. The more amount of TGF-beta1 in samples, the less antibody bound by Biotin-conjugated TGF-beta1. Then Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The substrate solutions are added to the wells, respectively. And the color develops in opposite to the amount of TGF-beta1 in the sample. The color development is stopped and the intensity of the color is measured.
