Test principle:
This assay employs the competitive enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with an antibody specific to EBV-Rta-IgG. Standards or samples are then added to the appropriate microtiter plate wells with a Horseradish Peroxidase (HRP)-conjugated EBV-Rta-IgG and incubated. The competitive inhibition reaction is launched between with HRP labeled EBV-Rta-IgG and unlabeled EBV-Rta-IgG with the antibody. A substrate solution is added to the wells and the color develops in opposite to the amount of EBV-Rta-IgG in the sample. The color development is stopped and the intensity of the color is measured.

Specificity:
This assay has high sensitivity and excellent specificity for detection of Human EBV-Rta-IgG. No significant cross-reactivity or interference between Human EBV-Rta-IgG and analogues was observed.
Recovery:
Matrices listed below were spiked with certain level of recombinant Human EBV-Rta-IgG and the recovery rates were calculated by comparing the measured value to the expected amount of Human EBV-Rta-IgG in samples.

Precision:
Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision. Inter-assay Precision (Precision between assays) Three samples of known concentration were tested in forty separate assays to assess inter-assay precision. CV (%) = SD/meanX100 Intra-Assay: CV<8% Inter-Assay: CV<12%
Linearity:
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Human EBV-Rta-IgG and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Stability:
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 condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).
Sample collection and storage:
Serum: Use a serum separator tube (SST) and allow samples to clot for two hours at room temperature or overnight at 2 - 8°C before centrifugation for 15 minutes at 1000 × g. Remove serum and assay immediately or aliquot and store samples at ≤ -20°C. Avoid repeated freeze-thaw cycles. Plasma: Collect plasma using EDTA, or heparin as an anticoagulant. Centrifuge for 15 minutes at 1000 × g at 2 - 8°C within 30 minutes of collection. Assay immediately or aliquot and store samples at ≤ -20°C. Avoid repeated freeze-thaw cycles. Other biological fluids: Centrifuge samples for 20 minutes at 1000 × g. Remove particulates and assay immediately or store samples in aliquot at -20°C or -80°C. Avoid repeated freeze/thaw cycles.
Kits storage instructions:
Store at 2-8°C. Please refer to Instruction Manual.
