{"product_id":"new-product-230789","title":"Strep II Tag Mouse monoclonal antibody","description":"\u003cp\u003eStreptavidin is a tetrameric protein purified from Streptomyces avidinii. It has wide use in numerous molecular biological protocols dues to its strong affinity for biotin. The original Strep-tag (AWRHPQFGG) was a nine amino acid peptide with high specificity and affinity towards streptavidin which allows the simple purification of protein by use of affinity columns, but required addition to only the C-terminus of recombinant proteins. To also allow a Strep-tag to be placed at the N-terminus of recombinant proteins, it was re-engineered and re-named Strep-tag II.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Mouse \/ All","offer_id":47662930886936,"sku":"MB2017","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_c8e4ba3f-1292-4e72-bbe2-1120d1631082.jpg?v=1707499977","url":"https:\/\/danabiosci.com\/products\/new-product-230789","provider":"Dana Bioscience","version":"1.0","type":"link"}
