About this item
Interleukin 2 (IL-2) is an immunomodulatory cytokine that is produced by lymphocytes. IL-2 signals through the IL-2R receptor to induce activated T cell proliferation and promote T cell differentiation. IL-2 also stimulates the proliferation and differentiation of B cells, natural killer cells, monocytes, and macrophages.
- Produced from genetically modified E. coli
- Contains 134 amino acids
These research grade recombinant proteins are typically used as cytokines, growth factors and chemokines in cell based assays and cell culture.
Delivery: A certificate of analysis (COA) is supplied with each product shipped detailing purity, formulation, biological activity, endotoxin levels, reconstitution instructions and recommended storage conditions.
Caution: For research use only. Not for use in diagnostic or therapeutic procedures.
