  • Product overview

    Abcam’s Human Myeloperoxidase (MPO) in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Myeloperoxidase in cell culture supernatants, cell lysate, tissue homogenates, serum, plasma (heparin, EDTA), saliva and urine.

    A Myeloperoxidase specific mouse monoclonal antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells and incubated. A biotinylated detection polyclonal antibody from goat specific for Myeloperoxidase is then added followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. TMB is then used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the Human Myeloperoxidase amount of sample captured in plate.

  • Tested applicationsSuitable for: Sandwich ELISAmore details
  • PlatformMicroplate


  • FunctionPart of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity.
  • Involvement in diseaseDefects in MPO are the cause of myeloperoxidase deficiency (MPD) [MIM:254600]. MPD is an autosomal recessive defect that results in disseminated candidiasis.
  • Sequence similaritiesBelongs to the peroxidase family. XPO subfamily.
  • Cellular localizationLysosome.

Uterine aspirates were collected by aspiration with a Cornier Pipelle (Eurogine Ref. 03040200) in the office of the clinician or in the operating room prior to surgery and transferred to 1.5 ml microtubes. Phosphate buffer saline was added in a 1:1 (v/v) ratio and centrifuged at 2,500 rcf for 20 min in order to separate the soluble fraction (supernatant) from the solid fraction (pellet). The supernatants were kept at -80°C until use.
The concentrations of MPO in the soluble fraction of uterine aspirates were quantified with commercially available ELISA kit (Abcam, catalog number ab119605) according to the manufacturer´s protocol. As no results are available regarding the levels of these proteins in uterine aspirates, samples were diluted using five serial dilutions: 1:2, 1:10, 1:50, 1:300, 1:1500.
The same amount of total protein from 8 uterine aspirates was loaded in each well. All samples were assayed in duplicates using a microplate reader and values were reported as ng/mL. The mean absorbance for each set of duplicate standards and samples was calculated. The standard curve was plotted in a log10-log10 scale (see figure 1A). The CV (%) between the duplicates of the samples ranged from 4-13% (average of 7%). Concentration of MMP9 of uterine aspirates ranged from 2 to 1053 ng/ul (see figure 1B).

Thank you for contacting us. Cross-reactivity with other molecules such as VPO has not been tested, however the homology between the immunogen of the antibody in the kit and human VPO is 41%, much to low for cross-reactivity to occurs. Typically around...

Thank you for your enquiry.

I can confirm that this kit (ab119605: MPO Human ELISA Kit) has been tested for cross-reactivity with human samples. It doesn't work on mouse samples.

If you need any further assistance in the future, ple...
