BACKGROUND: IL-7 is an essential cytokine in T-cell development and homeostasis. It binds to the IL-7R receptor. a complex of the IL-7Ralpha (CD127) and common gamma (CD132) chains. There is significant interest in evaluating the expression of CD127 on human T-cells as it often decreased in medical conditions leading to lymphopenia. https://allfixelectricales.shop/product-category/thermal-cutout/
