IL-2 Protein, Mouse (HEK293, His-Avi)

IL-2 Protein is usually produces by antigen-activated CD4+ T cells, CD8+ T cells, NK cells and NKT cells. IL-2 Protein is involved in signaling pathways including JAK/STAT, inosine phosphate 3-kinase /PI3K, and mitogen-activated protein kinase /MAPK. IL-2 Protein, Mouse (HEK293, His-Avi) is the recombinant mouse-derived IL-2 protein, expressed by HEK293 , with N-His, N-Avi labeled tag. The total length of IL-2 Protein, Mouse (HEK293, His-Avi) is 149 a.a., with molecular weight of 27-30 kDa.

IL-2 is a receptor cytokine produced by activated CD4-positive helper T cells and plays its role by activating JAK/STAT, inosine phosphate 3-kinase /PI3K and mitogen-activated protein kinase /MAPK. IL-2 binds to receptor complexes consisting of high affinity trimers IL-2R (IL2RA/CD25, IL2RB/CD122 and IL2RG/CD132) or low affinity dimers IL-2R (IL2RB and IL2RG). IL-2 can increase the cytolytic activity of NK cells. Promote strong proliferation of activated B cells and immunoglobulin production. IL-2 is involved in differentiation and homeostasis of effector T cell subsets, including Th1, Th2, Th17, and memory CD8-positive T cells. IL-2 synthesis is strictly regulated by TCR and CD28 signaling at the mRNA level. It mediates the activation induced cell death (AICD) process. IL-2 can be used in the research of cancer immunotherapy^{[1][2][3][4][5][6]}.

Measured in a cell proliferation assay using CTLL-2 mouse cytotoxic T cells. The ED₅₀ for this effect is <1 ng/mL.
