Alexa Fluor^® 647 Rabbit Anti-Human IFN-γ Antibody (S-212-145)

Interferon gamma (IFN-γ) is a dimerized soluble cytokine and the only member of the type II class of interferons. It is primarily produced by CD4+ T helper 1 (Th1) cells, natural killer (NK) cells, and CD8+ cytotoxic T cells. The IFN-γ protein is encoded by the IFNG gene in humans and consists of approximately 160 amino acids, forming a noncovalently linked homodimer with a molecular weight of about 50 kDa. It plays a crucial role in regulating both innate and adaptive immunity by activating signaling pathways, such as the JAK-STAT pathway, in cells like macrophages and B cells. IFN-γ has antiviral, antibacterial, and antitumor properties and is involved in promoting inflammation and cell proliferation. However, its pleiotropic nature also means it can induce immunosuppressive effects, which limit its clinical use.
