Descripción general

Interleukin-2 (IL-2) is an α-helical cytokine belonging to T-helper cell type 1. It has a molecular weight of 15kDa. The IL2 gene is mapped to human chromosome 4q27.[1] IL-2 is originally called as T cell growth factor.[2]

Aplicación

Interleukin-2 human has been used:
  • in the stimulation of natural killer cells[3]
  • to study its ability to stimulate lymphocyte growth and prevent apoptosis[4]
  • as an antigen in enzyme-linked immunosorbent assay (ELISA), to analyse the human autoantibody reactivities in health and in type 1 diabetes mellitus[5]

Acciones bioquímicas o fisiológicas

Interleukin-2 (IL-2) is an immunomodulatory factor produced by certain subsets of T lymphocytes. This lympho­kine promotes long term growth of acti­vated T cells and related cell types. IL-2 plays a role in the activation and proliferation of NK cells, induces γ-inter­feron and B cell growth factor secretion, and modulates the expression of the IL-2 receptor.
Interleukin-2 (IL-2) is essential for proliferation of natural killer (NK) cells, lymphocytes and macrophages.[1] It plays a key role in the immune system functions such as NK cell-stimulated immune responses. IL-2 also mediates the essential functions of regulatory T cells. It is implicated in autoimmune disease.[6] IL-2 is associated with apoptosis and thus, possesses antitumor response.[7] It mediates CD41+ T-cells differentiation into T-helper cell 1 and 2 effector subsets, preventing T-helper 17 differentiation.[1]

Forma física

Lyophilized, 0.2 μm filtered, no additives.

Nota de análisis

The biological activity is measured by the dose-dependent stimulation of the proliferation of murine CTLL-2 cells.

Questions

1–7 of 7 Questions  

  1. How to calculate the number of Units in the vial?

    1 answer

    1. The EC50 has been determined by dose-dependent stimulation of the proliferation of murine CTLL-2 cells. The EC50 value can be used to determine activity. The EC50 value is listed on the lot specific Certificate of Analysis. Certificates of Analysis can accessed in the DOCUMENTATION section of the product detail page:

      https://www.sigmaaldrich.com/product/sigma/i2644#product-documentation

      The specific activity in Units/mg can be calculated by the following:
      Activity = 1 × 106 / ED50 (in ng/ml).
