It is expressed by CD4+ and CD8+ T cells, γδ T cells, B cells, dendritic cells, and eosinophils. IL-2\/IL-2R signaling is required for T-cell proliferation and other fundamental functions which are essential for the immune response. IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine activated killer cells, monocytes, macrophages and oligodendrocytes.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882253815987,"sku":"BK0240-10","price":256.94,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882253848755,"sku":"BK0240-50","price":813.32,"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_1feece97-80ee-4df6-87ef-c71ceb71a6dd.jpg?v=1702050140","url":"https:\/\/afsbio.com\/products\/recombinant-il-2-human-bk0240","provider":"AFSBio Inc.","version":"1.0","type":"link"}
