Its biological activity is pleiotropic and it has been shown to induce interferon-gamma production in KG-1 cells. The combination of this cytokine and IL12 has been shown to inhibit IL4 dependent IgE and IgG1 production, and enhance IgG2a production in B cells.Recombinant rat Interleukin-18 (rrIL-18) produced in E.coli is a single non-glycosylated polypeptide chain containing 159 amino acids. A fully biologically active molecule, rrIL-18 has a molecular mass of 18.4 kDa analyzed by reducing SDS-PAGE and is obtained by proprietary chromatographic techniques at GenScript.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882241757363,"sku":"BK0092-10","price":375.54,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882241790131,"sku":"BK0092-50","price":1317.65,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_8448834d-fe63-4894-b899-2c28e67606c9.jpg?v=1702049900","url":"https:\/\/afsbio.com\/products\/recombinant-il-18-rat-bk0092","provider":"AFSBio Inc.","version":"1.0","type":"link"}
