The test is intended as an aid to diagnosis, and additional tests are required to complete the diagnostic results.\u003cbr\/\u003eDESCRIPTION\u003cbr\/\u003eVP (KOH) Reagent Droppers is used for the identification of bacteria, in particular of the Enterobacteriaceae family, based on the production of acetylmethylcarbinol (acetoin) from glucose metabolism.\u003cbr\/\u003eKIT CONTENTS\u003cbr\/\u003e• 10 dropper bottles of sodium alpha naphthol (2.5 ml)\u003cbr\/\u003e• 10 dropper bottles of potassium hydroxide (2.5 ml).\u003cbr\/\u003ePRINCIPLE OF THE METHOD\u003cbr\/\u003eSome bacteria, when cultured in specific media such as MR-VP broth, metabolize glucose to produce acetylmethylcarbinol. Upon addition of the Voges-Proskauer reagents to a culture tube containing MR-VP broth, any acetylmethylcarbinol present is oxidized to methyl diacetylcarbinol, which reacts with creatine (in the broth) and forms a red-colored compound. \u003c\/p\u003e","brand":"LIOFILCHEM","offers":[{"title":"Default Title","offer_id":57603169747326,"sku":"LF87007","price":72.21,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0959\/4873\/4846\/files\/LF87007_--_000_44687.gif?v=1783431577","url":"https:\/\/www.securlab.it\/en\/products\/vp-koh-reagent-droppers-reagents-for-the-voges-proskauer-test-in-dropper-bottles-20x2-5-ml","provider":"Securlab","version":"1.0","type":"link"}
