Active Recombinant Pig IL2 Protein (Ala21-Thr154), C-His tagged, Animal-free, Carrier-free

• Cat.No.: IL2-196P
• Product Overview: Recombinant Pig IL2 Protein (Ala21-Thr154) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Description: Interleukin-2 (IL-2) is a four bundle, immuno-modulatory cytokine which is expressed predominately by antigen-simulated CD4+ T cells, CD8+ T cells, natural killer (NK) cells, and dendritic cells (DC). IL-2 plays a fundamental role in promoting NK cell proliferation, cytotoxicity, and B cells differentiation. IL-2 modulate T cell differentiation programs, promoting naïve CD4+ T cell differentiation into T helper-1 (Th1) and T helper-2 (Th2) cells.
• Source: E. coli
• Species: Pig
• Tag: C-His
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce proliferation in CTLL2 cells. The ED50 for this effect is < 0.5 ng/mL.
