Each subunit binds one biotin molecule with a KD of ~1×10-15 M. The preparation contains an N- and C-terminal shortened variant (core streptavidin) with improved properties concerning homogeneity, solubility, resistance towards proteolytic degradation and accessibility of the biotin binding pocket as compared to native streptavidin.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Others\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:\u0026gt; 98 % by SDS-PAGE and HPLC analyses\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSource\u003c\/b\u003e:Recombinant streptavidin from Streptomyces avidinii, produced in Escherichia coli.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Recombinant Streptavidin\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBiological activity\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSynonyms\u003c\/b\u003e:Streptavidin, Recombinant\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEndotoxin\u003c\/b\u003e:Less than 0.1 EU\/μg of rStreptavidin as determined by LAL method.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStorage\u003c\/b\u003e:-20ºC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e:MAEAGITGTW YNQLGSTFIV TAGADGALTG TYESAVGNAE SRYVLTGRYD SAPATDGSGT ALGWTVAWKN NYRNAHSATT WSGQYVGGAE ARINTQWLLT SGTTEANAWK STLVGHDTFT KVKPSAAS\u003c\/p\u003e\u003cp\u003e\u003cb\u003euniprot accession\u003c\/b\u003e:P22629\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMolecular weight\u003c\/b\u003e:Approximately 52, per tetramer.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e:Lyophilized in 1 mM potassium phosphate buffer pH 6.5.\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48653931905124,"sku":"CD00012","price":258.05,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_4ffdcd02-b7e5-45df-a8b3-f6afe83d3939.jpg?v=1782765358","url":"https:\/\/www.genebiosystems.com\/products\/recombinant-streptavidin","provider":"GeneBio ","version":"1.0","type":"link"}
