Detection Principle:

The double antibody sandwich ELISA method was used in this experiment. Anti human IL-7 monoclonal antibody is coated on the microplate. IL-7 in the sample and standard will bind to the antibody fixed on the plate, and the free components will be washed away; Horseradish peroxidase labeled anti human IL-7 multi antibody was added to combine with IL-7 bound on the microplate to form an immune complex, and the free components were washed away; Add the substrate solution (chromogenic agent), the color of the solution gradually turns blue, add the stop solution, the solution turns yellow and stops changing. The absorbance was measured with a microplate reader

Background:

IL-7 (Interleukin-7)is a cytokine that plays an important role in lymphocyte differentiation, proliferation, and survival. IL-7 is produced by stromal epithelial cells of the thymus, bone marrow, and intestine. It is mediated by IL-7 r alpha / CD127 and commonγ The receptor complex composed of chain signalsΓ C is also a subunit of the IL-2, -4, -9, -15, and -21 receptors. IL-7 helps maintain all primitive and memory T cells. Moreover, IL-7 is required for T cell dendritic cell interaction. In mice, IL-7 activation by IL-7 r alpha is essential for the development of both T and B cell lineages, whereas in humans, T cells are not required and B cell development is required.
