The microtiter plate provided in this kit has been pre-coated with VMA. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to VMA. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of VMA in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e\u003ch3\u003eTarget background\u003c\/h3\u003e\u003cp\u003eAlternative names include Vanillyl Mandelic Acid.\u003c\/p\u003e","brand":"ELK Biotechnology","offers":[{"title":"48T","offer_id":56184211341652,"sku":"ABM79097","price":236.41,"currency_code":"GBP","in_stock":true},{"title":"96T","offer_id":56184211374420,"sku":"ABM79096","price":334.17,"currency_code":"GBP","in_stock":true},{"title":"96T*5","offer_id":56184211407188,"sku":"ABM79098","price":1420.22,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/ELK8239-b-1.jpg?v=1782012301","url":"https:\/\/www.abmium.com\/products\/elk-elk8239-vma-vanillylmandelic-acid-elisa-kit","provider":"ABMIUM","version":"1.0","type":"link"}
