Product Info

• Predicted Species Reactivity: Homo sapiens|Human
• Application: Enzyme-linked Immunosorbent assay-Sandwich
• ELISA Kit Detection Method: Colorimetric
• ELISA Kit Duration: 3h
• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Target Of The Antiproliferative Antibody 1 (TAPA1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Target Of The Antiproliferative Antibody 1 (TAPA1). 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 Target Of The Antiproliferative Antibody 1 (TAPA1), 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 Target Of The Antiproliferative Antibody 1 (TAPA1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• ELISA Kit Range: 0.312-20ng/mL
• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Target Of The Antiproliferative Antibody 1 (TAPA1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Target Of The Antiproliferative Antibody 1 (TAPA1) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%
