　　Organism species Homo sapiens (Human) 腺苷脱氨酶(ADA)检测试剂盒Sample type Serum, plasma, tissue homogenates and other biological fluids. Format 96-well strip plate Assay length 4.5 hours Detection range 1.56-100ng/mL The standard curve concentrations used for the ELISA’s were 100ng/mL, 50ng/mL, 25ng/mL, 12.5ng/mL, 6.25ng/mL, 3.13ng/mL, 1.56ng/mL Sensitivity The minimum detectable dose of this kit is typically less than 0.59ng/mL.
　　Specificity This assay has high sensitivity and excellent specificity for detection of Adenosine Deaminase (ADA). No significant cross-reactivity or interference between Adenosine Deaminase (ADA) and analogues was observed. Recovery Matrices listed below were spiked with certain level of recombinant Adenosine Deaminase (ADA) and the recovery rates were calculated by comparing the measured value to the expected amount of Adenosine Deaminase (ADA) in samples.
　　Matrix Recovery range (%) Average(%) serum(n=5) 96-103 99 EDTA plasma(n=5) 87-94 91 heparin plasma(n=5) 79-97 88
　　Precision Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Adenosine Deaminase (ADA) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Adenosine Deaminase (ADA) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV腺苷脱氨酶(ADA)检测试剂盒samples spiked with appropriate concentration of Adenosine Deaminase (ADA) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

　　Stability The stability of 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. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end. Reagents and materials provided

Test principle The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with 腺苷脱氨酶(ADA)检测试剂盒an antibody specific to Adenosine Deaminase (ADA). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Adenosine Deaminase (ADA). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Adenosine Deaminase (ADA), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Adenosine Deaminase (ADA) in the samples is腺苷脱氨酶(ADA)检测试剂盒 then determined by comparing the O.D. of the samples to the standard curve.
