Biochem/physiol Actions

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.

Physical form

Lyophilized from a 0.2 μm filtered solution in 50 mM sodium phosphate buffer, pH 7.0, containing 0.1% human serum albumin per 0.1 mL of cytokine.

Analysis Note

The biological activity is tested in a cell proliferation assay using an IL-2 dependent murine cytotoxic T cell line, CTLL-2.
