Synonyms: Interleukin-2; T-Cell Growth Factor; TCGF; Aldesleukin
Accession: P60568
Description:The human IL-2 protein, also known as interleukin-2, is an important cytokine that plays a vital role in regulating the immune system. It is produced by activated T cells and stimulates the proliferation and activation of various immune cells, such as T cells, B cells, and natural killer cells. IL-2 also promotes the development of immune memory and enhances the effectiveness of the immune response against infections and cancers. In addition, IL-2 has been used therapeutically in the treatment of certain diseases, such as cancer and autoimmune disorders, to boost the immune system.
Source: HEK293 cells-derived human IL-2 protein, Ala21-Thr153, with N-terminal his tag.
Purity: ≥90% as determined by SDS-PAGE.
Endotoxin: < 1 EU per 1μg of the protein by the LAL method.
Predicted N terminal: Met.
Molecular Mass: The recombinant human IL-2 consists of 140 amino acids and has a calculated molecular mass of 17.35 kDa.
Formulation: Supplied as sterile PBS, pH 7.4.
SDS-PAGE:
Human IL-2R immobilized on CM5 chip can bind human IL-2, His tag, with an affinity constant of 3.84 x 10-7 M as determined in a SPR assay (Biacore 8K).
Handling: Centrifuge vial prior to opening.
Do not vortex after reconstitution.
