Human FE(Ferritin) ELISA Kit | ELK1214

For research use only.Not intended for diagnostic use.

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 an antibody specific to Ferritin(FE). Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Ferritin(FE). 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 Ferritin(FE), 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 Ferritin(FE) in the samples is then determined by comparing the OD of the samples to the standard curve.

Standard curve

Recovery

Matrices listed below were spiked with certain level of recombinant FE and the recovery rates were calculated by comparing the measured value to the expected amount of FE in samples.

 

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of FE and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
