      Intended use

      This ELISA kit can be applied to the in vitro quantitative determination of Human ANG1  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 ANG1 . 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 ANG1 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 ANG1 , 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 ANG1 . The concentration of Human ANG1 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 ANG1 . 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 ANG1  were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Human ANG1  were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Human ANG1  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) 85-98 91
      EDTA plasma (n=5) 91-104 96
      Cell culture media (n=5) 93-110 100

      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.
