Background: IL-2 is produced mainly by T- cells expressing the surface antigen CD4 following cell activation by mitogens or allogen. Interleukin-2 (IL-2) has multiple, sometimes opposing, functions during an inflammatory response. It is a potent inducer of T-cell proliferation and T- helper 1 (Th1) and Th2 effector T-cell differentiation and provides T cells with a long-lasting competitive advantage resulting in the optimal survival and function of memory cells. In a regulatory role, IL-2 is important for the development, survival, and function of regulatory T cells, it enhances Fas-mediated activation-induced cell death, and it inhibits the development of inflammatory Th17 cells. Thus, in its dual and contrasting functions, IL-2 contributes to both the induction and the termination of inflammatory immune responses.
Biological Activity: The ED50 was determined by the dose dependent stimulation of murine CTLL-2 cells is < 0.1 ng/ml, corresponding to a specific activity of > 1 x 10^7 units/mg.
Description: Recombinant IL-2 is a disulfide-linked monomeric protein consisting of 150 amino acid residues, and migrates as an approximately 17 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine Interleukin-2 mature chain was expressed in E. coli.
Endotoxin Level: <0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Format: lyophilized protein
Formulation: Lyophilized from 0.2 µm filtered PBS, pH 7.0.
Genbank: P04351
Purity: ≥95% by SDS-PAGE and HPLC
Reconstitution: Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage Stability: The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
Uniprot: P04351
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: Not applicable (BSL-1)
