原理

This assay employs a two-site sandwich ELISA to quantitate EBV-VCA-IgG in samples. An antibody specific for EBV-VCA-IgG has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any EBV-VCA-IgG present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for EBV-VCA-IgG is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of EBV-VCA-IgG bound in the initial step. The color development is stopped and the intensity of the color is measured.

特异性

This assay has high sensitivity and excellent specificity for detection of Human EBV-VCA-IgG. No significant cross-reactivity or interference between Human EBV-VCA-IgG and analogues was observed.
 

回收率

Matrices listed below were spiked with certain level of recombinant Human EBV-VCA-IgG and the recovery rates were calculated by comparing the measured value to the expected amount of Human EBV-VCA-IgG in samples.

精密度

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<13%

样本收集及储存

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.
 

注意事项

Store at 2-8°C. Please refer to Instruction Manual.
