Interleukin 2 (IL 2), also termed T-cell growth factor, is a member of the cytokine family. IL-2 is produced by CD4+ T cell, CD8+ T cells, gamma δ T cells, B cells, dendritic cells and eosinophils, and plays a vital role in key function of the immune system, tolerance and immunity, primarily via its potent stimulatory activity for T cells.
别名：aldesleukin; interleukin 2; interleukin-2
白细胞介素2 (Interleukin 2, IL 2)，又称t细胞生长因子。IL-2信号通过IL-2受体传递，IL-2受体是一个由树形亚基组成的复合物，被称为alpha, beta和gamma。成熟小鼠IL-2与人IL-2和大鼠IL-2的同源性分别为56%和73%。IL-2由CD4+ T细胞、CD8+ T细胞、γ δ T细胞、B细胞、树突状细胞和嗜酸性粒细胞产生，主要通过其对T细胞的强大刺激活性，在免疫系统、耐受和免疫的关键功能中发挥重要作用。因此，IL-2可能是自然抑制自身免疫的关键细胞因子。

Vaspin (Visceral Adipose-Specific SERPIN) is a newly described adipokine. Vaspin is also a unique insulin sensitizing adipocytokine in obesity. |
| Recombinant Human B2M Protein (Mammalian, C-6His)
β-2-Microglobulin (B2M) is a secreted protein with 1 Ig-like C1-type (immunoglobulin-like) domain which belongs to the beta-2-microglobulin family. B2M may adopt the fibrillar configuration of amyloid in certain pathologic states. |
| Recombinant Mouse E-Selectin/CD62E Protein (HEK293)
E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis. |
| Recombinant Human DPP4/CD26 (Mammalian, C-6His)
DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. |
| Recombinant Human USP14 (E.coli, N-6His)
USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1. |
