Product Brief

  • Introduction

    Boster's ELISA Kit is a competitive assay that can be used for the quantification of Free Nitrotyrosine in plasma, serum, cell lysates, urine, and other sample matrices. The ELISA utilizes an Nitrotyrosine-coated plate and an HRP-conjugated antibody for detection which allows for an assay range of 62.5 to 8000nM Free Nitrotyrosine, with a sensitivity of 50nM. The other highlights of this kit are a quick incubation time of 60 minutes, stable reagents, and an easy to use protocol.

    Cite This ProductNitrotyrosine ELISA Kit (Boster Biological Technology, Pleasanton CA, USA, Catalog # EK7116)
    Validated SpeciesAll Animals
    ApplicationELISA

    *Our Boster Guarantee covers the use of this product in the above tested applications.

    Cross ReactivityThere is no detectable cross-reactivity.
    Pack Size96wells/kit, with removable strips.

    Properties

    Sensitivity50 nM
    *Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive.
    Assay Range62.5 - 8000 nM
    *This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range.
    Sample TypeCell lysates, Plasma, Serum, Urine

    *The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine? ELISA kit should detect it. 
    **For protocol and tips regarding preparing your sample of interest, please check our ELISA sample preparation guide.
    StorageStore at 4°C.

    Background

    Nitrotyrosine has been identified as a marker of inflammation and NO production. Nitrotyrosine is formed in presence of the active metabolite NO. Various pathways including the formation of peroxinitrite lead to nitrotyrosine production. Since nitrotyrosine is a stable end product of peroxynitrite oxidation, assessment of its plasma concentration may be useful as a marker of NO-dependent damage in vivo. Since NOX is only an indicator for enhanced NO production, protein associated nitrotyrosine might be a more suitable marker for damage induced by reactive nitrogen intermediates derived from NO. Furthermore, most proteins have a longer half life in the circulation than NOX levels. The presence of nitrotyrosine has been detected in various inflammatory processes including atherosclerotic plaques, celiac disease, rheumatoid arthritis, chronic renal failure and septic shock. In normal plasma low, undetectable, levels of nitrotyrosine are present. Nitrosylation of the amino acid tyrosine occurs both for free tyrosine and for protein bound tyrosine.

Instructions

Intra/Inter Assay Precision

Intra-Assay Precision: Three samples of known concentration were assayed thirty times on one plate. The intra-assay coefficient of variation of the Nitrotyrosine ELISA has been determined to be <10%.
Inter-Assay Precision: Three samples of known concentration were assayed thirty times in three individual assays. The inter-assay coefficient of variation of the Nitrotyrosine ELISA has been determined to be <15%.

Assay Overview

1. Prepare standard and samples in the Sample and Standard Diluent.

2. Add 50 ?L of prepared standards and samples in triplicate to appropriate wells.

3. Add 50 ?L of the diluted antibody preparation to the appropriate wells.

4. Cover plate with Plate Cover and incubate at room temperature (20-25°C) for 1 hour.

5. Wash plate 4 times with 1X Wash Buffer.

6. Add 100 ?L of TMB Substrate to each well.

7. Cover plate and develop the plate in the dark at room temperature for 30 minutes.

8. Add 100 ?L of Stop Solution to each well.

9. Measure absorbance on a plate reader at 450 nm.

10. Plot the standard curve and calculate sample concentrations.
