    TSLPR Antibody (4A11) is a mouse monoclonal IgG2a kappa light chain antibody that detects the TSLPR protein of human origin by western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). Anti-TSLPR antibody (4A11) is available as the non-conjugated format. Thymic stromal lymphopoietin (TSLP) plays a crucial role in the immune system by promoting the development and differentiation of B cells, which are essential for adaptive immunity. TSLP protein is primarily located in the thymus and other lymphoid tissues, where epithelial cells secrete TSLP to act on various immune cells. This localization is significant because TSLP can influence the development of immune responses at the site where T cells mature, thereby shaping the overall immune landscape. TSLP exerts effects by binding to TSLPR receptor, forming a complex with IL-7 receptor alpha (IL-7Ra), which is critical for signaling pathways that lead to cell survival and proliferation. The interaction between TSLP and TSLPR is vital for maintaining immune homeostasis and preventing excessive inflammation, highlighting TSLPR′s importance in immune regulation.
