Assay Procedure Summary:
1. Prepare the reagents, standards, and samples needed for testing; 2. Aliquot 100 µl of diluted standard into the standard wells; 3. Aliquot 100 µl of Standard Diluent buffer into control (zero) well; 4. Add 100 µL/well sample to the microtiter plate, incubate 90 min at 37°C; 5. Then add 100 µL of the prepared detection solution A, incubate 1 h at 37°C; 6. After washing the plate 3 times, add 100 µL of the prepared detection solution B and incubate 30 min at 37°C; 7. After washing the plate 5 times, add 90 µL of substrate solution and incubate 10-20 min at 37°C; 8. Terminated by the addition of 50 µL stop solution, the absorbance was read at 450 nm by a microplate reader.

ELISA Kit Principle:
This kit is based on sandwich enzyme-Linked immuno-sorbent assay technology. An antibody is pre-coated onto a 96-well plate. Standards, test samples, and biotin-conjugated reagent are added to the wells and incubated. The HRP-conjugated reagent is then added, and the plate is incubated at suitable temperature. After TMB substrate is added, only wells that contain sufficient INHBA will produce a blue coloured product, which then changes to yellow after adding the Acidic stop solution. The intensity of the yellow colour is proportional to the INHBA amount bound on the plate. The OD is measured by spectrophotometry at a wavelength of 450nm ± 10nm, from which the concentration of INHBA can be calculated.
