Horseradish peroxidase is a 44,173.9-dalton glycoprotein with six lysine residues which can be conjugated to a labeled molecule. It produces a coloured, fluorimetric [6] or luminescent derivative of the labeled molecule when incubated with a proper substrate, allowing it to be detected and quantified.
3,3′,5,5′-Tetramethylbenzidine or TMB is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays . [1] TMB is a white solid that forms a pale blue-green liquid in solution with ethyl acetate.
This enzyme complex then catalyzes the conversion of the enhanced chemiluminescent substrate into a sensitized reagent in the vicinity of the molecule of interest, which on further oxidation by hydrogen peroxide, produces a triplet (excited) carbonyl, which emits light when it decays to the singlet carbonyl. Enhanced chemiluminescence allows ...
Horseradish peroxidase is also capable of oxidizing these substrates, but its heme is not covalently bound and becomes damaged during turnover. [ 4 ] A specific vanadium bromoperoxidase in marine organisms (fungi, bacteria, microalgae, perhaps other eukaryotes) uses vanadate and hydrogen peroxide to brominate electrophilic organics.
Peroxidase can be used for treatment of industrial waste waters. For example, phenols, which are important pollutants, can be removed by enzyme-catalyzed polymerization using horseradish peroxidase. Thus phenols are oxidized to phenoxy radicals, which participate in reactions where polymers and oligomers are produced that are less toxic than ...
Animal heme-dependent peroxidases is a family of peroxidases.Peroxidases are found in bacteria, fungi, plants and animals. On the basis of sequence similarity, a number of animal heme peroxidases can be categorized as members of a superfamily: myeloperoxidase (MPO); eosinophil peroxidase (EPO); lactoperoxidase (LPO); thyroid peroxidase (TPO); prostaglandin H synthase (PGHS); and peroxidasin.
Secondary antibodies can be conjugated to enzymes such as horseradish peroxidase (HRP) or alkaline phosphatase (AP); or fluorescent dyes such as fluorescein isothiocyanate (FITC), rhodamine derivatives, Alexa Fluor dyes; or other molecules to be used in various applications.
Horseradish sauce made from grated horseradish root and vinegar is a common condiment in the United Kingdom, in Denmark (with sugar added) and in Poland. [30] In the UK, it is usually served with roast beef, often as part of a traditional Sunday roast , but can be used in a number of other dishes, including sandwiches or salads.
