IL-35 ELISA kits are assays designed to detect interleukin 35 (IL-35), a member of the IL-12 family of cytokines. It is a multi-subunit complex consisting of an alpha chain and a beta chain. This cytokine is secreted by regulatory T cells and B cells, and can suppress T cell proliferation. IL-35 has shown immunomodulatory activity against diseases such as psoriasis, systemic lupus erythematosus, and rheumatoid arthritis. Cellular signaling of IL-35 occurs largely via the transcription factor STAT 1. IL-35 ELISA kits are useful for studying autoimmune disease progression and T regulatory cell (Treg) activity.
