　　紅細胞生成素(EPO)檢測試劑盒 ELISA Kit for Erythropoietin (EPO) FOR IN VITRO AND RESEARCH USE ONLY, NOT FOR USE IN CLINICAL DIAGNOSTIC PROCEDURES! Organism species Homo sapiens (Human) Product No. SEA028Hu Sample type Serum, plasma, tissue homogenates, cell lysates and other biological fluids. Format 96-well strip plate Assay length 4.5 hours Detection range 3.13-200pg/mL The standard curve concentrations used for the ELISA’s were 200pg/mL, 100pg/mL, 50pg/mL, 25pg/mL, 12.5pg/mL, 6.25pg/mL, 3.13pg/mL Sensitivity The minimum detectable dose of this kit is typically less than 1.36pg/mL.
　　Specificity This assay has high sensitivity and excellent specificity for detection of Erythropoietin (EPO). No significant cross-reactivity or interference between Erythropoietin (EPO) and analogues was observed. Recovery Matrices listed below were spiked with certain level of recombinant Erythropoietin (EPO) and the recovery rates were calculated by comparing the measured value to the expected amount of Erythropoietin (EPO) in samples. Matrix Recovery range (%) Average(%) serum(n=5) 95-104 101 EDTA plasma(n=5) 86-95 91 heparin plasma(n=5) 78-98 86 Precision Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Erythropoietin (EPO) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Erythropoietin (EPO) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12% Linearity The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Erythropoietin (EPO) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected. Sample 1:2 1:4 1:8 1:16 serum(n=5) 87-94% 91-101% 84-98% 81-101% EDTA plasma(n=5) 80-89% 93-101% 80-97% 85-93% heparin plasma(n=5) 78-103% 88-95% 83-91% 91-105% 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.

The microtiter plate provided in this kit has been pre-coated with an antibody specific to Erythropoietin (EPO). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Erythropoietin (EPO). 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 Erythropoietin (EPO), 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 &plusmn; 10nm. The concentration of Erythropoietin (EPO) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
