{"product_id":"r30721","title":"Kallistatin Antibody","description":"\u003cp\u003eSerpina 4, also called Kallistatin, is a protein that in humans is encoded by the SERPINA4 gene. It is a member of the serpin superfamily and represents a major inhibitor of human tissue kallikrein in circulation. Kallistatin is a serine proteinase inhibitor (serpin) and a heparin-binding protein. It is localized in vascular smooth muscle cells and endothelial cells of blood vessels, suggesting that it may be involved in the regulation of vascular function.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Rabbit","offer_id":49476816503064,"sku":"R30721","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_2cf02ba9-411a-49f1-9419-81be794cf051.jpg?v=1734483801","url":"https:\/\/danabiosci.com\/products\/r30721","provider":"Dana Bioscience","version":"1.0","type":"link"}
