It can increase production and mobilization of eosinophils and CD34+ progenitors from the bone marrow. IL-5 plays an important role in inducing cell-mediated immunity against parasitic infections and certain tumors. IL-5 also promotes differentiation of basophils and primes them for histamine and leukotriene release.Recombinant rat Interleukin-5 (rrIL-5) produced in E.coli is a disulfide-linked homodimer containing two non-glycosylated polypeptide chains of 113 amino acids each.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cspan class=\"bhp-cat-pill\"\u003eE. coli Expression\u003c\/span\u003e\n\u003cp\u003eRecombinant IL-5 Rat protein is produced using a validated E. coli expression system and supplied as lyophilized powder for long-term stability.
