  • 蛋白结构(Molecular Characterization)

    IL-2 Structure

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 19.1 kDa. The protein migrates as 22-25 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 偶联(Conjugate)

    Unconjugated

  • 内毒素(Endotoxin)

    Less than 1.0 EU per μg by the LAL method.

  • 纯度(Purity)

    90% as determined by SDS-PAGE.

  • 制剂(Formulation)

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

    IL-2 SDS-PAGE

    Mouse IL-2, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).

  • 活性(Bioactivity)-ELISA

     IL-2 ELISA

    Immobilized Mouse IL-2, His Tag (Cat. No. IL2-M52H3) at 5 μg/mL (100 μL/well) can bind Mouse IL-2RB&IL-2RA&IL-2RG, Fc Tag&Fc Tag (Cat. No. ILG-M5253) with a linear range of 0.8-3 ng/mL (QC tested).

    Protocol
  • 活性(Bioactivity)-SPR

     IL-2 SPR

    Mouse IL-2, His Tag (Cat. No. IL2-M52H3) immobilized on CM5 Chip can bind Mouse IL-2 R beta, Fc Tag (Cat. No. ILB-M5253) with an affinity constant of 36.2 μM as determined in a SPR assay (Biacore 8K) (Routinely tested).

背景介绍

Interleukin-2 (IL-2) is an interleukin, a type of cytokine immune system signaling molecule, which is a leukocytotrophic hormone that is instrumental in the body's natural response to microbial infection and in discriminating between foreign (non-self) and self. IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes, the cells that are responsible for immunity. Mature human IL-2 shares 56% and 66% aa sequence identity with mouse and rat IL-2, respectively. Human and mouse IL-2 exhibit crossspecies activity. The receptor for IL-2 consists of three subunits that are present on the cell surface in varying preformed complexes. IL-2 is also necessary during T cell development in the thymus for the maturation of a unique subset of T cells that are termed regulatory T cells (T-regs). After exiting from the thymus, T-Regs function to prevent other T cells from recognizing and reacting against "self antigens", which could result in "autoimmunity". T-Regs do so by preventing the responding cells from producing IL-2. Thus, IL-2 is required to discriminate between self and non-self, another one of the unique characteristics of the immune system.
