Alexa Fluor® 488 Mouse Anti-Human CD25 Antibody (S-R494)

CD25, also known as IL2RA, is the alpha chain of the interleukin-2 receptor, a heterotrimeric protein complex that also includes beta (IL2RB) and the common gamma chain (IL2RG). It is a membranous glycoprotein primarily expressed on activated T lymphocytes and plays a crucial role in immune homeostasis by interacting with interleukin-2, a pleiotropic cytokine. CD25 is involved in the proliferation of T and B lymphocytes and is essential for the assembly of the high-affinity interleukin-2 receptor. In addition to its role in the immune system, CD25 is also expressed on certain non-immune cells and has been identified as a potential therapeutic target in cancers.
