Description

General description

Recombinant human Interleukin‑4 (IL‑4) is a pleiotropic cytokine expressed in E. coli and supplied as a lyophilized protein. IL‑4 is commonly used in mammalian cell culture research to study immune cell differentiation and cytokine‑mediated signaling pathways in vitro.

Application

Recombinant human IL‑4 has been used in mammalian cell culture research applications involving growth and differentiation of immunologically competent cells and VEGF‑induced and βFGF‑induced angiogenesis.

Physical form

Lyophilized from a sterile filtered solution.

Analysis Note

The biological activity is measured by the dose-dependent stimulation of the proliferation of human TF-1 cells.
