Transforming growth factor (TGF) play a crucial role in tissue regeneration, cell differentiation, embryonic development, and regulation of the immune system. Transforming growth factor beta is found in hematopoietic (blood-forming) tissue and initiates a signaling pathway that suppresses the early development of cancer cells. It enhances the deposition of extracellular matrix and may play potential role in wound healing and cirrhosis formation. Many cells synthesize TGF-b and almost all of them have specific receptors for this peptide.

This quantitative assay employs sandwich ELISA method. Microwells are pre-coated with antibodies against TGF-b1. The diluted patient samples (after activation) are added into the wells and any TGF-b1 present remains bound to the plate. After washing the wells, peroxidase labeled anti-TGF-b1 antibodies are added. Bound conjugate is visualized with TMB substrate and intensity of color is proportional to the concentration of TGF-b1 in the sample. Stop dilution is added to each well to stop the reaction.
