Product Summary
The Quantikine Mouse soluble VEGF R1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse sVEGF R1 in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant mouse VEGF R1 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse sVEGF R1 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring mouse sVEGF R1.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

The recovery of mouse sVEGF R1 spiked to three levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Supernates (n=6) 96 82-110
EDTA Plasma (n=6) 106 92-120
Serum (n=6) 106 96-119
To assess the linearity of the assay, six samples containing and/or spiked with high concentrations of mouse sVEGF R1 in each matrix were diluted with Calibrator Diluent and then assayed.

Background: VEGF R1/Flt-1

VEGF R1 (Flt-1), VEGF R2 (KDR/Flk-1), and VEGF R3 (Flt-4) belong to the class III subfamily of receptor tyrosine kinases (RTKs). All three receptors contain seven immunoglobulin-like repeats in their extracellular domain and kinase insert domains in their intracellular region. They are best known for regulating VEGF family-mediated vasculogenesis, angiogenesis, and lymphangiogenesis. They are also mediators of neurotrophic activity and regulators of hematopoietic development. VEGF R2 is thought to be the primary inducer of VEGF-mediated blood vessel growth, while VEGF R3 plays a significant role in VEGF-C and VEGF-D-mediated lymphangiogenesis.

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 50 µL Assay Diluent
    4.   Add 50 µL of Assay Diluent to each well.

    5. 50 µL Standard, Control, or Sample
    6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
    7.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

    8. 100 µL Conjugate
    9.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
    10.   Aspirate and wash 5 times.

    11. 100 µL Substrate Solution
    12.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    13. 100 µL Stop Solution
    14.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
