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.

At the amino acid sequence level, human mature BTC protein exhibits 80% identity with mouse BTC protein. BTC is expressed in most tissues including kidney, uterus, liver and pancreas. It is also present in body fluids, including serum, milk, and colostrum.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5µg","offer_id":42882223538355,"sku":"PR1006-5","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"20µg","offer_id":42882223571123,"sku":"PR1006-20","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_e03c0126-73a3-4c0c-96f1-e31f1f534a56.jpg?v=1702049571","url":"https:\/\/afsbio.com\/products\/recombinant-human-betacellulin-rhubtc-pr1006","provider":"AFSBio Inc.","version":"1.0","type":"link"}
