    Product Description

     

    Interleukin-2 (IL-2) is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. It is expressed by CD4+ and CD8+ T cells, γδ T cells, B cells, dendritic cells, and eosinophils. IL-2/IL-2R signaling is required for T- cell proliferation and other fundamental functions which are essential for the immune response. The receptor for IL-2 consists of three subunits (55 kDa IL-2Rα, 75 kDa IL-2Rβ, and 64 kDa common gamma chain γc/IL-2Rγ) that are present on the cell surface in varying preformed complexes. Mature human IL-2 shares 56% and 66% amino acid sequence identity with mouse and rat IL-2, respectively. Human and mouse IL-2 exhibit cross-species activity.

    Sterile Filtered White lyophilized (freeze-dried) powder.

    Purity

    > 97% by SDS-PAGE and HPLC analyses.

    Biological Activity

    The ED50 as determined by a cell proliferation assay using murine CTLL-2 cells is less than 0.2 ng/mL, corresponding to a specific activity of > 5.0 × 106 IU/mg. Fully biologically active when compared to standard.

    Endotoxin

    < 1.0 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 μm filtered concentrated solution in 10 mM sodium citrate, pH 4.0.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions


    Avoid repeated freeze-thaw cycles.
