Batches of this product that have a concentration < 1mg/ml may have BSA added as a stabilising agent. If you would like information about the formulation of a specific lot, please contact our scientific support team who will be happy to help.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 175 kDa.
Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
FunctionGenerates hydrogen peroxide which is required for the activity of thyroid peroxidase/TPO and lactoperoxidase/LPO. Plays a role in thyroid hormones synthesis and lactoperoxidase-mediated antimicrobial defense at the surface of mucosa. May have its own peroxidase activity through its N-terminal peroxidase-like domain.
Tissue specificityExpressed in colon, small intestine, duodenum and tracheal surface epithelial cells (at protein level). Expressed in thyrocytes. Also detected in kidney, liver, lung, pancreas, prostate, salivary glands, rectum and testis.
Involvement in diseaseDefects in DUOX2 are a cause of thyroid dyshormonogenesis 6 (TDH6) [MIM:607200]. A disorder due to a defective conversion of accumulated iodide to organically bound iodine. The iodide organification defect can be partial or complete.
Sequence similaritiesIn the N-terminal section; belongs to the peroxidase family. Contains 3 EF-hand domains. Contains 1 FAD-binding FR-type domain. Contains 1 ferric oxidoreductase domain.
Developmental stageWidely expressed in fetal tissues.
Cellular localizationApical cell membrane. Localizes to the apical membrane of epithelial cells.
IHC image of DUOX2 staining in Rat thyroid formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab97266, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
