      Intended use

      This ELISA kit can be applied to the in vitro quantitative determination of Human BMP-4  concentrations in serum, plasma and other biological fluids.

      Test principle

      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-4 . 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-4 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-4 , 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-4 . The concentration of Human BMP-4 in samples can be calculated by comparing the OD of the samples to the standard curve.

      Specificity

      This kit recognizes some recombinant and natural Human BMP-4 . No significant cross-reactivity or interference was observed.

      Typical data

      For convenience in result calculation, absorbance can be used as ordinate and standard concentrations as abscissa. The standard curve provided in the manual is only for reference, and experimenters should draw the standard curve based on data of themselves.

      Precision

      Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high leve Human BMP-4  were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Human BMP-4  were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Human BMP-4  spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.

      Sample Type Range (%) Average Recovery (%)
      Serum (n=5) 91-102 97
      EDTA plasma (n=5) 91-104 97
      Cell culture media (n=5) 90-103 96

      Linearity

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