Heme-oxygenase is a ubiquitous enzyme that catalyzes the initial and rate-limiting steps in heme catabolism yielding equimolar amounts of biliverdin, iron and carbon monoxide. Biliverdin is subsequently converted to bilirubin and the free iron is sequestered to ferritin. These products have important physiological effects as carbon monoxide is a potent vasodilator; biliverdin and bilirubin are potent antioxidants; and the free iron increases oxidative stress and regulates the expression of many mRNAs. There are three isoforms of heme-oxygenase, HO-1, HO-2 and HO-3; however HO-1 and HO-2 are the major isoforms as they both have been identified in mammals. HO-1, also known as heat shock protein 32, is an inducible isoform activated by most oxidative stress inducers, cytokines, inflammatory agents and heat shock. HO-2 is a constitutive isoform which is expressed under homeostatic conditions. HO-1 is also considered to be a cytoprotective factor in that free heme is highly reactive and cytotoxic, and secondly, carbon monoxide is a mediator inhibiting the inflammatory process and bilirubin is a scavenger for reactive oxygen, both of which are the end products of heme catalyzation. It has also been shown that HO-1 deficiency may cause reduced stress defense, a pro-inflammatory tendency, susceptibility to atherosclerotic lesion formation, endothelial cell injury, and growth retardation. Up-regulation of HO-1 is therefore said to be one of the major defense mechanisms of oxidative stress.

Human, Mouse, Rat, Bovine, Dog, Guinea Pig, Hamster, Monkey, Pig, Rabbit
Conjugated Peptide
HO-1 Antibody was produced in mice by repeated immunizations raised against a human HO-1 synthetic peptide corresponding to the C-terminus region.
Anti-HO-1 Antibody was purified by Protein G chromatography. A BLAST analysis was used to suggest cross-reactivity with HO-1 from Human, Mouse, Bovine, Canine, Guinea pig, Hamster, Monkey, Pig, Rabbit, and Rat based on 100% homology with the immunizing sequence. Does not cross-react with HO-2. Cross-reactivity with HO-1 from other sources has not been determined. Oxidative Stress research.
P09601 - UniProtKB

Application Details

Anti-HO-1 Antibody has been tested for WB, IP, IF microscopy, and IHC. Expect a band approximately 32kDa protein, corresponding to the molecular mass of HO-1 on SDS Page immunoblots. Specific conditions for reactivity should be optimized by the end user.
