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.

It shares 61% aa sequence identity with mature rat IGF-II. Circulating IGF-I is produced by hepatocytes, while local IGF-I is produced by many other tissues in which it has paracrine effects. IGF-I induces the proliferation, migration, and differentiation of a wide variety of cell types during development and postnatally.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"10µg","offer_id":42882231468211,"sku":"PR3006-10","price":0.0,"currency_code":"CAD","in_stock":true},{"title":"50µg","offer_id":42882231500979,"sku":"PR3006-50","price":0.0,"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_4ed13d96-43b2-4979-bec9-53287f4f2a50.jpg?v=1702049740","url":"https:\/\/afsbio.com\/products\/recombinant-rat-insulinlike-growth-factor-i-rrtigf-1-pr3006","provider":"AFSBio Inc.","version":"1.0","type":"link"}
