背景（Background）
T helper cells (Th) play a vital role in the adaptive immune system by suppressing or regulating immune responses. After Th actived, it will differentiate into T-helper 1 (Th1) or T-helper 2 (Th2) effector cells. These two subsets are characterized by their distinct cytokine expression pattern and the immune function they mediate. Th1 and Th2 cells each produce a specialized combination of cytokines that depends on type of pathogen that the helper T cell has recognized—some cytokines are more effective than others in the process of eliminating certain invaders. In general, TH1 cytokines play the role of immune killing, while Th2 cytokines play the role of immune protection. Th1/Th2 paradigm provides rationale for developing new vaccines against infectious diseases and novel strategies for the therapy of allergic and autoimmune disorders.
应用说明（Application）
The Human Th1 Cytokine Kit can be used to quantitatively measure Interleukin-2 (IL-2), Interleukin-6 (IL-6), Tumor Necrosis Factor-α (TNF-α), and Interferon-γ (IFN-γ) protein levels in a single sample.The kit performance has been optimized for analysis of specific cytokines in tissue culture supernatants, EDTA plasma, and serum samples.
It is for research use only.
