Upon receipt, store at 4°C. Reconstitute with ddH 2 O and store at 4°C. Upon reconstitution, the product is in 20 mM KPi (pH 6.5). Avoid multiple freeze\/thaw cycles .\n\u003cb\u003eSpecificity \/ Sensitivity\u003c\/b\u003e\nStreptavidin has a remarkably high affinity for its natural ligand, biotin. The complex and irregular structure of the biotin-binding site makes it highly optimized for biotin binding and confers great specificity to the streptavidin-biotin complexes (4).\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nStreptavidin is a protein that is derived from the bacteria .\n\u003cb\u003eBackground\u003c\/b\u003e\nStreptavidin is a 53 kDa homotetramer isolated from for use in isolation and detection bioassays (3). Each streptavidin subunit forms high affinity non-covalent bonds with the vitamin biotin. Because of its strong non-covalent interaction with biotin, streptavidin can be used to isolate and detect biotinylated proteins (1,2).","brand":"CST","offers":[{"title":"Default Title","offer_id":46800785801385,"sku":"78319S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-78319s","provider":"Iright","version":"1.0","type":"link"}
