Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg\/mL. Stock solutions should be apportioned into working aliquots and stored at \u0026lt;-20°C. Further dilutions should be made in appropriate buffered solutions.\u003c\/p\u003e\n\n\u003cp\u003eStorage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze\/thaw cycles.\u003c\/p\u003e\n\n\u003cp\u003eUsage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China\u003c\/p\u003e\n\n\u003cp\u003eDescription: Epigen is an EGF-related polypeptide growth factor that signals through the ErbB receptor-1. 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 14.7 kDa transmembrane precursor protein, which is processed by proteolytic cleavage to produce a mature soluble sequence.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5µg","offer_id":42882224390323,"sku":"PR1020-5","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"20µg","offer_id":42882224423091,"sku":"PR1020-20","price":490.83,"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_0463b803-b246-4175-974c-004de41497bc.jpg?v=1702049592","url":"https:\/\/afsbio.com\/products\/recombinant-human-epigen-rhuepg-pr1020","provider":"AFSBio Inc.","version":"1.0","type":"link"}
