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\u003eInsulin-like growth factor-1 (IGF-1) is the principal hormonal mediator of statural growth. Under normal circumstances, growth hormone (GH) binds to its receptor in the liver, and other tissues, and stimulates the synthesis\/secretion of IGF-1. In target tissues, the Type 1 IGF receptor, which is homologous to the insulin receptor, is activated by IGF-1, leading to intracellular signaling which stimulates multiple processes leading to statural growth. The metabolic actions of IGF-1 are in part directed at stimulating the uptake of glucose, fatty acids, and amino acids so that metabolism supports growing tissues. The LR3 is a long-term analog of human IGF-1, specifically designed and manufactured for mammalian cell culture to support large-scale manufacturing of recombinant biopharmaceuticals.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"20µg","offer_id":42880591855795,"sku":"PR1080-20","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"100µg","offer_id":42880591888563,"sku":"PR1080-100","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_edb748c1-428f-4c05-a171-8983f4d29932.jpg?v=1701982015","url":"https:\/\/afsbio.com\/products\/recombinant-human-long-r3-insulin-like-growth-factor-1-rhulr3igf-1-pr1080","provider":"AFSBio Inc.","version":"1.0","type":"link"}
