Test Principle

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human FSH. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human FSH and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human FSH, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human FSH. You can calculate the concentration of Human FSH in the samples by comparing the OD of the samples to the standard curve.

The recovery of Human FSH spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range (%) Average Recovery (%)
Serum(n=8) 85-96 91
EDTA plasma (n=8) 90-101 95
Cell culture media (n=8) 92-103 97


Samples were spiked with high concentrations of Human FSH and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.

A***********SSubmitted [ Mar 11 2023 ]

Asked: Can this kit be used to test salivary FSH? And what considerations should be taken (should saliva be centrifuged first? Saliva storage before using it on this kit?)



adminSubmitted [ Mar 11 2023 ]

Answered: Hi Abdulrahman, We have verified human saliva samples with E-EL-H1143, and the detection value are very low, and most of the OD values are no signal. It is not recommended to use this kit to detect saliva samples. Here are the recommendations for collection and preservation of saliva samples: Patients should fast and gargle one hour before sampling to keep the mouth clean. Saliva samples should be centrifuged at 2-8℃, 12000r/min for 10 minutes to remove impurities, and take the supernatant for detection. It is recommended to use fresh saliva samples for testing. Samples could be stored for one month at - 20 ℃ and three months at - 80 ℃. If any further questions, pls email to Best regards
