Human Hepatitis D Virus Antibody IgG(HDV IgG) ELISA Kit

Intended Use

This kit is used to assay the Hepatitis D Virus Antibody IgG(HDV IgG)in the sample of Human’s serum, blood plasma, and other related tissue Liquid.

Test principle

The kit uses a double-antigen sandwich enzyme-linked immunosorbent assay (ELISA) to assay the level of Human Hepatitis D Virus Antibody IgG(HDV IgG) in samples . Add Human Hepatitis D Virus Antibody IgG(HDV IgG) to pre-coated Human Hepatitis D Virus Antibody IgG microelisa well, incubation; washing. Add HRP tagged Human Hepatitis D Virus Antibody IgG. After another incubation and washing, remove the unbound enzyme, Then add Chromogen Solution A, B, the color of the liquid change into the blue, And at the effect of acid the color finally become yellow. Using the micro plate reader of 450nm wavelength to measure the absorbency (OD value), and comparing with the critical value to determine the existence of the Human Hepatitis D Virus Antibody IgG(HDV IgG) of the sample.

Materials supplied in the Test Kit

Materials required but not supplied

1. 37 ℃ incubator 2. Standard Enzyme reader

3. Precision pipettes and Disposable pipette tips 4. Distilled water

5. Disposable tubes for sample dilution 6. Absorbent paper

Important Notes

1.The kit takes out from the 2-8℃ environment ,should be balanced 30 minutes in the room temperature then use. If the microelisa stripplate has not use up after opened, the plate should be stored in Sealed bag.

2.Add Sample with sampler Each step, And proofread its accuracy frequently, avoids the experimental error.

3.Recommended that all standard materials, test samples are doing double.If the testing material content in the sample is excessively high ,please use Sample dilution to dilute certain multiple (n times),then assay. Please multiply total dilution times when calculate(×n×5)

4.The operation carried out in strict accordance with instructions, test results must be based on microplate reader to determine readings shall prevail

5.In order to avoid cross-contamination, to avoid re-use in the hands of the suction head and seal plate membrane

6.Other agents do not have to be packaged or covered,This reagent which different batch number component do not mix.

Manually washing method

shake away the remain liquid in the enzyme plates; place some bibulous papers on the test-bed, and flap the plates on the upside down strongly. Inject at least 0.35ml after-dilution washing solution into the well, and marinate 1~2 minutes. Repeat this process according to your requirements.

Automatic washing method

if there is automatic washing machine, it should only be used in the test when you are quite familiar with its function and performance.

Specimen requirements

1.Samples containing NaN3 must not be tested as it inhibits the activity of Horse Radish Peroxidase (HRP).

2.After collecting the sample, extraction should be immediately carried out in accordance with related documents. After extraction, experiment should be conducted immediately as well. Otherwise, keep the sample at -20℃. Avoid repeated freeze-thaw cycles.

3.Serum: Allow the serum to clot for 10-20 minutes at room temperature. Centrifuge (at 2000-3000 RPM) for 20 minutes. Collect the supernatants carefully. When sediments occurred during storage, centrifugation should be performed again.

4.Blood plasma: In accordance with the requirements of sample collection, EDTA or sodium citrate should be used as anti coagulation. Add EDTA or sodium citrate and mix them for 10-20 minutes. Centrifuge (at 2000-3000 RPM) for approximately 20 minutes. Collect the supernatants carefully. When sediments occurred during storage, centrifugation should be performed again.

5.Urine: Collect by sterile tube. Centrifuge (at 2000-3000 RPM) for approximately 20 minutes. Collect the supernatants carefully. When sediments occurred during storage, centrifugation should be performed again. When collecting pleuroperitoneal fluid and cerebrospinal fluid, please follow the procedures above-mentioned.

6.Cell culture supernatant: Collect by sterile tubes when examining secrete components. Centrifuge (at 2000-3000 RPM) for approximately 20 minutes. Collect the supernatants carefully. When examining the components within the cell, use PBS (PH 7.2-7.4) to dilute cell suspension to the cell concentration of approximately 1 million/ml. Damage cells through repeated freeze-thaw cycles to let out the inside components. Centrifuge (at 2000-3000 RPM) for approximately 20 minutes. Collect the supernatants carefully. When sediments occurred during storage, centrifugation should be performed again.

7.Tissue sample: Incise sample and weigh up. Add a certain amount of PBS (PH 7.4). Freeze with liquid nitrogen immediately for later use. Thaw the sample and keep it at 2-8℃. Add a certain amount of PBS (PH 7.4) and then homogenize the sample thoroughly by hand or homogenizer. Centrifuge (at 2000-3000 RPM) for approximately 20 minutes. Collect the supernatants carefully. Aliquot and keep one for examination and freeze the others for later use.
