Diammonium 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate), e masani ona taʻua o le ABTS, o se mea e masani ona faʻaaogaina chromogenic substrate i suʻesuʻega o meaola, aemaise lava ile vaega ole enzymology.O se mea faʻapipiʻi e faʻaaogaina e fua ai le gaioiga o enzymes eseese, e aofia ai peroxidases ma oxidases.
O le ABTS e leai se lanu i lona fa'ama'i fa'ama'i ae e liu lanumoana-lanumeamata pe a fa'ama'iina e se enzyme pe a iai le hydrogen peroxide po'o le okesene mole.O lenei suiga lanu e mafua ona o le faʻavaeina o se cation radical, lea e mitiia le malamalama i le fusi o alaleo.
Ole tali ile va ole ABTS ma le enzyme e maua mai ai se oloa lanu e mafai ona fua ile spectrophotometrically.O le malosi o le lanu e fa'atatau tonu i le gaioiga enzymatic, e mafai ai e tagata su'esu'e su'esu'e ona iloilo fa'atusatusaga o le enzyme kinetics, enzyme inhibition, po'o fegalegaleaiga enzyme-substrate.
ABTS o lo'o i ai le tele o fa'aoga i vaega eseese, e aofia ai su'esu'ega fa'afoma'i, su'esu'ega fa'afoma'i, ma su'esu'ega o mea'ai.E sili ona maaleale ma ofoina atu le tele o le faʻaogaina o mea, ma avea ai ma filifiliga taʻutaʻua mo le tele o suʻega biochemical.
