The IL-27 protein together with IL23A forms IL-23 interleukin, a key cytokine in innate and adaptive immunity. It is associated with infection responses, binds to IL12RB1 and IL23R receptor complexes, and activates Jak-Stat signaling. IL-27 Protein, Mouse (228a.a, HEK293, His, solution) is the recombinant mouse-derived IL-27, expressed by HEK293, with C-10*His labeled tag.
