Properties

Assay type Sandwich-ELISA
Format 96T/48T
Assay time 3.5h
Detection range 31.25-2000 pg/mL
Sensitivity 18.75 pg/mL
Sample type &Sample volume serum, plasma and other biological fluids; 100μL
Specificity This kit recognizes Rat VEGF-A in samples. No significant cross-reactivity or interference between Rat VEGF-A and analogues was observed.
Reproducibility Both intra-CV and inter-CV are < 10%.
Application This ELISA kit applies to the in vitro quantitative determination of Rat VEGF-A concentrations in serum, plasma and other biological fluids.

Test Principle

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

Kit components & Storage

An unopened kit can be stored at 2-8℃ for 1 month. If the kit is not supposed to be used within 1 month, store the components separately according to the following conditions once the kit is received.

Recovery

The recovery of Rat VEGF-A spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range (%) Average Recovery (%)
Serum(n=8) 86-101 93
EDTA plasma (n=8) 90-102 95
Cell culture media (n=8) 89-101 95

Linearity

Samples were spiked with high concentrations of Rat VEGF-A and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
