QC198, QuantiGlo Immunoassay Control Set 732 for Human VEGF - Please Inquire
The QuantiGlo Human VEGF Chemiluminescent Immunoassay is a 5.5 hour solid phase ELISA designed to measure VEGF165 levels in cell culture supernates, serum, plasma, saliva, and urine. It contains Sf 21-expressed recombinant human VEGF165 and antibodies raised against the recombinant protein. Results obtained for naturally occurring human VEGF and recombinant human VEGF121 showed linear curves that were parallel to the standard curves obtained using the QuantiGlo kit standards. These results indicate that this kit can be used to determine relative mass values for natural human VEGF.
Intra-Assay Precision (Precision within an assay) Four samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Four samples of known concentration were tested in separate assays to assess inter-assay precision.
The recovery of VEGF spiked to three different levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Media (n=4)
EDTA Plasma (n=4)
Heparin Plasma (n=4)
To assess the linearity of the assay, samples containing or spiked with high concentrations of VEGF in various matrices were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
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.
