    Purpose
    The kit is a competitive inhibition enzyme immunoassay technique for the in vitro quantitative measurement of EDN2 in rat serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids.
    Sample Type
    Cell Culture Supernatant, Cell Lysate, Plasma, Serum, Tissue Homogenate
    Analytical Method
    Quantitative
    Specificity
    This assay has high sensitivity and excellent specificity for detection of this index.
    Cross-Reactivity (Details)
    No significant cross-reactivity or interference between this index and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross- reactivity detection between this index and all the analogues, therefore, cross reaction may still exist.
    Sensitivity
    2.96 pg/mL

    Assay Procedure

    This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to the index has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled the index and unlabeled the index (Standards or samples) with the pre-coated antibody specific to the index. After incubation the unbound conjugate is washed off. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of the index in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of the index in the sample.

    Assay Precision
    • Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
    • Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
    • CV(%) = SD/meanX100
    • Intra-assay: CV<10%
    • Inter-assay: CV<12%
    Restrictions
    For Research Use only
  • Precaution of Use
    The Stop Solution suggested for use with this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material.
    Handling Advice
    The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5 % within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
    Storage
    4 °C,-20 °C
    Storage Comment
    The Assay Plate, Standard, Detection Reagent A and Detection Reagent B should be stored at -20°C upon being received. After receiving the kit , Substrate should be always stored at 4°C.Other reagents are kept according to the labels on vials. But for long term storage, please keep the whole kit at -20°C. The unused strips should be kept in a sealed bag with the desiccant provided to minimize exposure to damp air. The test kit may be used throughout the expiration date of the kit (six months from the date of manufacture). Opened test kits will remain stable until the expiring date shown, provided it is stored as prescribed above.
    Expiry Date
    12 months
