HMOX1 (Heme Oxygenase 1, HO-1, HO, HO1)

Cat no: H1847-69S

HMOX1 (Heme Oxygenase 1, HO-1, HO, HO1)

Heme oxygenase-1 (HO-1) or HSP32 is the inducible isoform of heme oxygenase which catalyzes the NADPH, O2 and cytochrome P450 reductase dependent oxidation of heme to carbon monoxide, iron and biliverdin that is immediately reduced to bilirubin. These products of the HO reaction have important physiological effects: carbon monoxide is a potent vasodilator; biliverdin and its product bilirubin are potent antioxidants; "free" iron increases oxidative stress and regulates the expression of many mRNAs (e.g., DCT-1, ferritin and transferrin receptor) by affecting the conformation of iron regulatory protein (IRP)-1 and its binding to iron regulatory elements (IREs) in the 5'-or 3'-UTRs of the mRNAs. To date, three heme oxygenase isoforms HO-1, HO-2 and HO-3 have been identified. HO-1, also known as Hsp32, a major heat shock/stress response protein, is ubiquitous and its mRNA as well as its activity can be increased several-fold by heme, other metalloporphyrins, transition metals and stimuli that induce cellular stress.\n\nApplications:\nSuitable for use in Western Blot and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nImmunohistochemistry (Formalin fixed paraffin embedded): 10ug/ml\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
