It is produced in several tissues, including the testis, liver, heart and in certain tumor cells. Epigen is mitogenic for fibroblasts and epithelial cells. Human Epigen is initially synthesized as a glycosylated precursor protein, which is processed by proteolytic cleavage to produce a mature soluble sequence.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10μg","offer_id":42882248573107,"sku":"BK0197-10","price":217.41,"currency_code":"CAD","in_stock":true},{"title":"50μg","offer_id":42882248605875,"sku":"BK0197-50","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_329baf50-c102-47e5-ae48-ae6308a989c1.jpg?v=1702050050","url":"https:\/\/afsbio.com\/products\/recombinant-epigen-human-cho-expre-ssed-bk0197","provider":"AFSBio Inc.","version":"1.0","type":"link"}
