IL-3 shares similarities with Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) and IL-5: they all have a four-helix bundle structure, are located on the same chromosomes in both human and mouse, are produced by activated T cells, and share receptors. The IL-3\/IL-5\/GM-CSF receptor family members are all heterodimeric, composed of a receptor-specific α chain and a common β chain. IL-3 is also called multi-colony stimulating factor since it stimulates the development and colony formation of multiple lineages of hematopoietic cells by activating intracellular pathways such as Ras-Raf-ERK and JAK\/STAT. IL-3 inhibits apoptosis and promotes cell survival by targeting the anti-apoptotic bcl-2 gene family. Recombinant rat Interleukin-3 beta (rrIL-3 beta) produced in E.coli is a single non-glycosylated polypeptide chain containing of 144 amino acids. A fully biologically active molecule, rrIL-3 beta has a molecular mass of 16.3 kDa analyzed by non-reducing SDS-PAGE and is obtained by proprietary chromatographic techniques at GenScript.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882243035315,"sku":"BK0105-10","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882243068083,"sku":"BK0105-50","price":691.77,"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_2c4b0e91-11cb-4d41-8c85-7f36ddd4f306.jpg?v=1702049925","url":"https:\/\/afsbio.com\/products\/recombinant-il-3%ce%b2-rat-bk0105","provider":"AFSBio Inc.","version":"1.0","type":"link"}
