Human Heme Oxygenase 1 ELISA Kit (ab207621) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Heme Oxygenase 1 protein in cell culture extracts, cell culture supernatant, serum, tissue extracts, cit plasma, edta plasma, and hep plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Heme Oxygenase 1 with 7.9 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
This kit recognizes both native and recombinant human Heme Oxygenase 1 protein in serum, plasma, cell culture supernatant, and cell and tissue extract samples.
This kit recognizes human Heme Oxygenase 1 protein.
Other species reactivity was determined by measuring 50% (dilution) serum samples of various species, interpolating the protein concentrations from the human standard curve, and expressing the interpolated concentrations as a percentage of the protein concentration in human serum assayed at the same dilution. Reactivity < 3% was determined for the following species: Mouse , Rat , Hamster, Guinea Pig , Dog, Goat, Pig, Cow
Heme oxygenase 1 (HO 1) is an enzyme that functions in heme catabolism. The activity of heme oxygenase 1 is to cleave the heme ring to form biliverdin. There are two isozymes of heme oxygenase that have 56% amino acid sequence identity: inducible heme oxygenase 1 and constitutively expressed heme oxygenase 2.

RelevanceFunction: Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase. Under physiological conditions, the activity of heme oxygenase is highest in the spleen, where senescent erythrocytes are sequestrated and destroyed. Exhibits cytoprotective effects since excess of free heme sensitizes cells to undergo apoptosis. Tissue specificity: Expressed at higher levels in renal cancer tissue than in normal tissue (at protein level). Disease: Heme oxygenase 1 deficiency Similarity: Belongs to the heme oxygenase family.

The concentrations of Heme Oxygenase 1 were measured in duplicate, interpolated from the Heme Oxygenase 1 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 50%, plasma (EDTA) 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Heme Oxygenase 1 concentration was determined to be 1.37 ng/mL in serum and 2.12 ng/mL in plasma (EDTA).
The concentrations of Heme Oxygenase 1 were measured in duplicate and interpolated from the Heme Oxygenase 1 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Heme Oxygenase 1 concentration was determined to be 3.30 ng/mL in liver homogenate extract and 1.60 ng/mL in A549 cell extract.
Interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Heme Oxygenase 1 concentration was determined to be 1,630 pg/mL with a range of 391 – 3,198 pg/mL.
Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Native Heme Oxygenase 1 was measured in the following biological samples in a 2-fold dilution series. Sample dilutions are made in Sample Diluent NS.
