VEGF (Vascular endothelial growth factor) is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. It is required for regulating the proliferation, migration, and survival of embryonic endothelial cells and during wound healing and the female reproductive cycle in adults. Pathologically, it is involved in tumor development and tumor vascular leakage. VEGF binds to VEGF R1/Flt-1, VEGF R2/Flk-1/KDR, and Neuropilin-1. Multiple forms of VEGF are generated by alternative splicing and proteolysis.

Product Features
Magnetic Luminex High Performance Assays are flexible bead-based multiplex assays. They allow up to 50 user-defined target analytes to be simultaneously profiled using cell culture supernates, serum, or plasma samples. Some panels are also validated with human milk, saliva, and/or urine samples.
- Simultaneously profile Human VEGF with a panel of related analytes in one sample
- Magnetic format allows for easier wash steps
- Undergoes similar validation testing as Quantikine® ELISA Kits
- Precise and Specific
- Requires a small sample volume (<50 µL)
- Run your assay in just 3-5 hours
- Mass-calibrated standards for consistent results with every new lot of material
- Enough reagents for one 96-well plate
- Quick turn-around time: Kits are typically shipped within 2-3 days of ordering*
*Please allow additional time for international orders.
Performance Validation
R&D Systems Luminex High Performance Assays undergo our most extensive validation testing. All Luminex High Performance Assay Panels are validated for use with serum and plasma samples. Some High Performance Assays are additionally validated for cell culture supernatants, milk, saliva, or urine, as indicated on the individual product data sheets. Luminex High Performance Assays are tested for sensitivity (three-quarters the low standard), intra-assay precision, inter-assay precision, and to ensure assay linearity for validated sample types. Recovery values for individual samples in validated sample types are also tested. Validation data for each analyte can be found in the product datasheet.

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

Which Luminex Assay is Right for Me?
Assays for the Luminex platform are offered as High Performance Assays or Discovery Assays.
High Performance Assays are optimized and validated as complete panels with a focused set of analytes. You can choose from Fixed Panels, Premixed options, or Configurable User Mix formats depending on your needs.
Discovery Assays deliver maximum flexibility, enabling the creation of fully customized panels tailored to your research needs. With universal reagents validated for compatibility across all analytes in the menu, they support endless customization possibilities.
Additional Information About Luminex Assays
All R&D Systems Luminex Assays are designed for use with any Luminex instrument including MAGPIX, Luminex 200, FLEXMAP 3D, and the INTELLIFLEX.
Luminex assays use color-coded, magnetic microparticles coated with analyte-specific antibodies to enable multiplex quantitation. During the assay, standards and samples are added to the wells, where target analytes bind to the capture antibodies. A biotinylated detection antibody cocktail is then introduced, followed by a Streptavidin-PE conjugate that generates a fluorescent signal proportional to the amount of analyte present.
Each microparticle is identified by a unique signature and the signal intensity is measured using a Luminex instrument. These assays are designed to deliver reliable and reproducible results with validated antibody pairs and optimized protocols. They are well suited for applications that require sensitivity, accuracy, and confidence in your data while enabling efficient multiplexing to measure multiple targets simultaneously.

Sample Tested: EDTA Plasma and CTAD PlasmaVerified Customer | Posted 01/23/2017The Assay performes well (concerning reproducibility, precision), human EDTA Plasma samples can be quantified, CTAD plasma samples are usually below the detection limit. But sensitivity is not as good as given in the datasheets and on the website. While the Quantikine ELISA is calibrated against reference material this assay is probably not calibrated. When cross-testing the standard from the Quantikine VEGF kit (#DVE00), it can be seen that the sensitivty needs to be correded by a factor of approx. 3. Would be great if the standards provided with the different VEGF kits would be all be calibrated against each other which would allow a better comparison of real assay sensitivity.
