產(chǎn)品概述：
特異性：This assay has high sensitivity and excellent specificity for detection of Human CA199. No significant cross-reactivity or interference between Human CA199 and analogues was observed.
回收率：Matrices listed below were spiked with certain level of recombinant Human CA199 and the recovery rates were calculated by comparing the measured value to the expected amount of Human CA199 in samples.
線性：The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Human CA199 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
穩(wěn)定性：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).
測試原理：This assay employs a two-site sandwich ELISA to quantitate CA199 in samples. An antibody specific for CA199 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyCA199 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CA199 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 CA199 bound in the initial step. The color development is stopped and the intensity of the color is measured.
