Assay Procedure Summary:
1. Prepare the reagents, standards, and samples needed for testing; 2. Aliquot 50 µl of diluted standard into the standard wells; 3. Aliquot 50 µl of Standard Diluent buffer into control (zero) well; 4. Add 50 µL/well sample to the microtiter plate; 5. Then add 50 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 competitive 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. A competitive inhibition reaction takes place between the biotin-labelled INHBA/INHBB and the unlabelled-INHBA/INHBB on the pre-coated antibody. 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/INHBB will produce a blue coloured product, which then changes to yellow after adding the acidic stop solution. The intensity of the color yellow is inversely proportional to the INHBA/INHBB amount bound on the plate. The OD is measured by spectrophotometry at a wavelength of 450nm ± 10nm, from which the concentration of INHBA/INHBB can be calculated.
