This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human BMP-3. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human BMP-3 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human BMP-3, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding 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 BMP-3. The concentration of Human BMP-3 in samples can be calculated by comparing the OD of the samples to the standard curve.

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

- Set standard, test sample and control (zero) wells on the pre-coated plate and record theirpositions. It is recommended to measure each standard and sample in duplicate. Note: addall solutions to the bottom of the plate wells while avoiding contact with the well walls. Ensuresolutions do not foam when adding to the wells.
- Aliquot 100 µL of standard solutions into the standard wells.
- Add 100 µL of Sample / Standard dilution buffer into the control (zero) well.
- Add 100 µL of properly diluted sample (serum, plasma, tissue homogenates and otherbiological fluids) into test sample wells.
- Cover the plate with the sealer provided in the kit and incubate for 90 min at 37 °C.
- Aspirate the liquid from each well, do not wash. Immediately add 100 µL of BiotinylatedDetection Ab working solution to each well. Cover the plate with a plate seal and gently mix. Incubate for 1 hour at 37 °C.
- Aspirate or decant the solution from the plate and add 350 µL of wash buffer to each welland incubate for 1-2 minutes at room temperature. Aspirate the solution from each well andclap the plate on absorbent filter paper to dry. Repeat this process 3 times. Note: a microplatewasher can be used in this step and other wash steps.
