La mieloperoxidasa (MPO) es una peroxidasa única que, además de su actividad de peroxidación, también cataliza la conversión de peróxido de hidrógeno (H2O2) y cloruro (Cl-) en ácido hipocloroso (HOCl). El Kit de ensayo de actividad de la mieloperoxidasa (MPO) EnzChek™ ofrece ensayos para la determinación de las actividades de cloración y peroxidación de la MPO en solución y en lisados celulares. Para la detección de cloración, el kit incluye fluoresceína 3'-(p-aminofenil) (APF) no fluorescente, que se escinde selectivamente con hipoclorito (-OCl) para producir fluoresceína. La peroxidación se detecta utilizando el reactivo Amplex™ UltraRed no fluorescente (A36006), que se oxida con los intermediarios redox generados por H2O2 MPO-I y MPO-II para formar un producto fluorescente. El Kit de ensayo de actividad de la mieloperoxidasa EnzChek™ se puede utilizar para detectar continuamente estas actividades a temperatura ambiente en un amplio rango dinámico (de 1,5 a 200 ng/ml). La velocidad (30 minutos), la sensibilidad y la comodidad de mezclar y leer hacen que este kit sea ideal para medir las actividades de la MPO y para la detección de alto rendimiento de inhibidores específicos de la MPO.
Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

Preguntas frecuentes
What is the dynamic range of the EnzChek Myeloperoxidase (MPO) Activity Assay Kit (Cat. No. E33856)?
The EnzChek Myeloperoixdase Activity Assay Kit (Cat. No. E33856) can detect myeloperoxidase activity at a broad dynamic range of 1.5 to 200 ng/mL.
What can interfere with the EnzChek Myeloperoxidase (MPO) Activity assay?
MPO is inhibited by azide, diclofenac, methimazole, quercetin, rutin, and salicylhydroxamic acid. Make certain that samples do not include sodium azide. Endogenous catalases can interfere with the assay; catalase activity may be inhibited by using 3-amino-1,2,4-triazole. Detergents, common components in cell lysis buffers, should be avoided; use freeze/thawing and/or mechanical methods to lyse cells.
Cytochrome P-450 (CYP)-derived epoxyeicosatrienoic acids (EETs) possess potent anti-inflammatory effects in vitro. However, the effect of increased CYP-mediated EET biosynthesis and decreased soluble epoxide hydrolase (sEH, Ephx2)-mediated EET hydrolysis on vascular inflammation in vivo has not been rigorously investigated. Consequently, we characterized acute vascular inflammatory responses to endotoxin in transgenic ... More
G-CSF treatment of severe congenital neutropenia reverses neutropenia but does not correct the underlying functional deficiency of the neutrophil in defending against microorganisms.

'The treatment of children affected by severe congenital neutropenia (SCN) with G-CSF strongly reduces the risk of sepsis by reversing neutropenia. However, SCN patients who respond to the treatment with the growth factor still have an elevated risk of succumbing to sepsis. Because the disease is usually caused by heterozygous ... More
Targeted deletion of tumor suppressor PTEN augments neutrophil function and enhances host defense in neutropenia-associated pneumonia.

'Neutropenia and related infections are the most important dose-limiting toxicities in anticancer chemotherapy and radiotherapy. In this study, we explored a new strategy for augmenting host defense in neutropenia-related pneumonia. Phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P(3)) signaling in neutrophils was elevated by depleting PTEN, a phosphatidylinositol 3''-phosphatase that hydrolyzes PtdIns(3,4,5)P(3). In myeloid-specific PTEN knockout ... More
Inflammation-induced, 3'UTR-dependent translational inhibition of Hsp70 mRNA impairs intestinal homeostasis.

'Although the inducible heat shock protein 70 (Hsp70) is essential for maintaining intestinal homeostasis in colitis, it is translationally downregulated in inflamed colonic mucosa, paradoxically rendering the gut more susceptible to injury. We examined the basis for this process by analyzing the role of untranslated regions (UTR) of Hsp70 mRNA ... More
Functional consequence of positive selection revealed through rational mutagenesis of human myeloperoxidase.
'Myeloperoxidase (MPO) is a member of the mammalian heme peroxidase (MHP) multigene family. Whereas all MHPs oxidize specific halides to generate the corresponding hypohalous acid, MPO is unique in its capacity to oxidize chloride at physiologic pH to produce hypochlorous acid (HOCl), a potent microbicide that contributes to neutrophil-mediated host ...
