IgA ELISA Kit

Produktnummer ABIN364594

Produktdetails IgA ELISA Kit

Target: IgA

Reaktivität: Rind (Kuh)

Nachweismethode: Colorimetric

Methodentyp: Competition ELISA

Detektionsbereich: 0.39-25 μg/mL

Untere Nachweisgrenze: 0.39 μg/mL

Applikation: ELISA

Verwendungszweck: This immunoassay kit allows for the in vitro quantitative determination of bovine IgA concentrations in serum ,plasma, cell culture supernates and tissue homogenates.

Proben: Serum, Plasma, Cell Culture Supernatant, Tissue Homogenate

Analytische Methode: Quantitative

Spezifität: This assay recognizes bovine IgA.

Kreuzreaktivität (Details): Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between the target antigen and all analogues for other species. Therefore, cross reaction may still exist.

Sensitivität: 0.39 μg/mL

Anwendungsinformationen

Applikationshinweise:

• The supplier is only responsible for the kit itself, but not for the samples consumed during the assay. The user should calculate the possible amount of the samples used in the whole test. Please reserve sufficient samples in advance.
• Samples to be used within 5 days may be stored at 2-8°C, otherwise samples must be stored at -20°C (≤ 1 month) or -80°C (≤ 2 months) to avoid loss of bioactivity and contamination.
• Grossly hemolyzed samples are not suitable for use in this assay.
• If the samples are not indicated in the manual, a preliminary experiment to determine the validity of the kit is necessary.
• Please predict the concentration before assaying. If values for these are not within the range of the standard curve, users must determine the optimal sample dilutions for their particular experiments.
• Tissue or cell extraction samples prepared by chemical lysis buffer may cause unexpected ELISA results due to the impacts of certain chemicals.
• Owing to the possibility of mismatching between antigens from another resource and antibodies used in this supplier's kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by this supplier's products.
• Influenced by factors including cell viability, cell number and cell sampling time, samples from cell culture supernatant may not be recognized by the kit.
• Fresh samples without long time storage are recommended for the test. Otherwise, protein degradation and denaturalization may occur in those samples and finally lead to wrong results.

Detection wavelength: 450 nm

Information on standard material:
Depending on the antigen to be detected, standards can be either native or recombinant protein. The recombinant proteins are being expressed in CHO cells in most cases. Please inquire for more information. The formulation of auxiliary material in the standard is considered proprietary information, however it does not contain any poisonous substance. Proclin 300 (1:3000) is used as preservative.

Information on reagents:
In most cases the stop solution provided is 1 N H2SO4. The formulation of wash solution is proprietary information. None of the components contain (sodium) azide, thimerosal, 2-mercaptoethanol (2-ME) or any other poisonous materials. For the sandwich method kits, the sample diluent, antibody diluent, enzyme diluent and standard all contain BSA.

Information on antibodies:
The antibodies provided in different kits vary in regards to clonality and host. Some antibodies are affinity purified, some are Protein A

Probenmenge: 50 μL

Testdauer: 1 - 4.5 h

Plattentyp: Pre-coated

Protokoll: The microtiter plate provided in this kit has been pre-coated with bovine IgA. Standards or samples are then added to the appropriate microtiter plate wells with Horseradish Peroxidase (HRP) -conjugated antibody preparation specific for bovine IgA， mix well and incubated. The more the amount of bovine IgA in samples, the less HRP- conjugated antibody preparation specific for bovine IgA bound by pre-coated bovine IgA. Then a TMB (3,3',5,5' tetramethyl-benzidine) substrate solution is added to each well. And the color develops in opposite to the amount of bovine IgA in the sample. The color development is stopped and the intensity of the color is measured.

Testpräzision: Intra-assay precision (precision within an assay): Three samples of known concentration were tested twenty times on one plate to assess precision.
Inter-assay precision (precision between assays): Three samples of known concentration were tested in twenty assays to assess precision.

• Intra-assay: CV% less than 8%
• Inter-assay: CV% less than 10%

Beschränkungen: Nur für Forschungszwecke einsetzbar

Handhabung

Vorsichtsmaßnahmen: The Stop Solution provided with this kit is an acid solution. Wear eye, hand, face and clothing protection when using this material.

Handhabung:

• The kit should not be used beyond the expiration date on the kit label.
• Do not mix or substitute reagents with those from other lots or sources.
• If samples generate values higher than the highest standard, dilute the samples with Sample Diluent and repeat the assay.
• Any variation in Sample Diluent, operator, pipetting technique, washing technique, incubation time/temperature and kit age can cause variation in binding.
• This assay is designed to eliminate interference by soluble receptors, binding proteins and other factors present in biological samples. Until all factors have been tested in the Immunoassay, the possibility of interference cannot be excluded.

Lagerung: 4 °C/-20 °C

Informationen zur Lagerung: For unopened kit: All the reagents should be kept according to the labels on vials.

Haltbarkeit: 6 months
