Alexa Fluor® 488 Mouse Anti-Human CD70 Antibody (Ki-24)

CD70, also known as CD27 ligand, is a type Ⅱ transmembrane protein that plays a crucial role in the immune system. It is primarily expressed on antigen - presenting cells (APCs) such as dendritic cells, macrophages, and B cells, as well as on activated T cells. CD70 interacts with its receptor CD27, which is mainly found on T cells, B cells, and natural killer (NK) cells. This interaction provides important co - stimulatory signals that promote T cell activation, proliferation, and differentiation, and also enhances B cell and NK cell functions. Additionally, CD70 is involved in the regulation of immune responses, including the maintenance of immune homeostasis and the induction of immune - mediated tumor cell killing. Abnormal expression of CD70 has been associated with various diseases, such as autoimmune disorders and certain types of cancers. Therefore, CD70 is considered a promising target for the development of immunotherapies.
