    Fonction
    This assay employs the competitive inhibition enzyme immunoassay technique. An antibody specific for Immunoglobulin A (IgA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between Horseradish Peroxidase (HRP) labeled Immunoglobulin A (IgA) and unlabeled Immunoglobulin A (IgA) (Standards or samples) with the pre-coated antibody specific for Immunoglobulin A (IgA). After incubation the unbound conjugate is washed off. The amount of bound HRP conjugate is reverse proportional - the concentration of Immunoglobulin A (IgA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional - the concentration of Immunoglobulin A (IgA) in the sample.

  • Indications d'application
    • Limited by the current condition and scientific technology, we cannot completely conduct the comprehensive identification and analysis on the raw material provided by suppliers. So there might be some qualitative and technical risks to use the kit.
    • The final experimental results will be closely related to validity of the products, operation skills of the end users and the experimental environments. Please make sure that sufficient samples are available.
    • Kits from different batches may be a little different in detection range, sensitivity and color developing time.
    • Do not mix or substitute reagents from one kit lot to another. Use only the reagents supplied by manufacturer.
    • Protect all reagents from strong light during storage and incubation. All the bottle caps of reagents should be covered tightly to prevent the evaporation and contamination of microorganism.
    • There may be some foggy substance in the wells when the plate is opened at the first time. It will not have any effect on the final assay results. Do not remove microtiter plate from the storage bag until needed.
    • Wrong operations during the reagents preparation and loading, as well as incorrect parameter setting for the plate reader may lead to incorrect results. A microplate plate reader with a bandwidth of 10nm or less and an optical density range of 0-3 O.D. or greater at 450 ± 10nm wavelength is acceptable for use in absorbance measurement. Please read the instruction carefully and adjust the instrument prior to the experiment.
    • Even the same operator might get different results in two separate experiments. In order to get better reproducible results, the operation of every step in the assay should be controlled. Furthermore, a preliminary experiment before assay for each batch is recommended.
    • Each kit has been strictly passed Q.C test. However, results from end users might be inconsistent with our in-house data due to some unexpected transportation conditions or different lab equipments. Intra-assay variance among kits from different batches might arise from above factors, too.
    • Kits from different manufacturers for the same item might produce different results, since we have not compared our products with other manufacturers.

    Information on standard material:
    The standard might be recombinant protein or natural protein, that will depend on the specific kit. Moreover, the expression system is E.coli or yeast or mammal cell. There is 0.05% proclin 300 in the standard as preservative.

    Information on reagents:
    The stop solution used in the kit is sulfuric acid with concentration of 1 mol/L. And the wash solution is TBS. The standard diluent contains 0.02 % sodium azide, assay diluent A and assay diluent B contain 0.01% sodium azide. Some kits can contain is BSA in them.

    Information on antibodies:
    The provided antibodies and their host vary in different kits.

    Précision du teste

    Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Immunoglobulin A (IgA) were tested 20 times on one plate, respectively.
    Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Immunoglobulin A (IgA) were tested on 3 different plates, 8 replicates in each plate.
    CV(%) = SD/meanX100
    Intra-Assay: CV<10%

    Restrictions
    For Research Use only
  • Précaution d'utilisation
    The Stop Solution suggested for use with this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material.
    Conseil sur la manipulation
    The stability of 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 condition.
    To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

    • For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20°C upon receipt while the others should be at 4°C.
    • For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal.
      Note: It is highly recommended to use the remaining reagents within 1 month provided this is within the expiration date of the kit.
    • For ELISA kit, 1 day storage at 37°C can be considered as 2 months at 4°C, which means 3 days at 37°C equaling 6 months at 4°C.
    Date de péremption
