Reproducibility
Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Defensin Alpha 3, Neutrophil Specific (DEFa3) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Defensin Alpha 3, Neutrophil Specific (DEFa3) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Target
Defensin 2 and defensin 3 have antibiotic, fungicide and antiviral activities. Has antimicrobial activity against Gram-negative and Gram-positive bacteria. Defensins are thought to kill microbes by permeabilizing their plasma membrane.
Type
ELISA Kit
Applications
Enzyme-linked Immunosorbent assay-Sandwich
Detection Method
Colorimetric
Assay 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 Defensin Alpha 3, Neutrophil Specific (DEFa3) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Defensin Alpha 3, Neutrophil Specific (DEFa3) . 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 Defensin Alpha 3, Neutrophil Specific (DEFa3), 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 Defensin Alpha 3, Neutrophil Specific (DEFa3) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
