Anwendungsinformationen

Kommentare:

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.

Testdauer: 3 h

Plattentyp: Pre-coated

Protokoll: 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 Dickkopf Related Protein 4 (DKK4). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Dickkopf Related Protein 4 (DKK4). 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 Dickkopf Related Protein 4 (DKK4), 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 Dickkopf Related Protein 4 (DKK4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Testpräzision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Dickkopf Related Protein 4 (DKK4) were tested 20 times on one plate, respectively
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Dickkopf Related Protein 4 (DKK4) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Beschränkungen: Nur für Forschungszwecke einsetzbar

Handhabung

Handhabung: The Stop Solution is acidic. Do not allow to contact skin or eyes. Calibrators, controls and specimen samples should be assayed in duplicate. Once the procedure has been started, all steps should be completed without interruption.
