Description: This Human sVEGF-R1 FlowCytomix Simplex Kit is designed for the measurement of human sVEGF-R1 in a bead based immunoassay analyzed on a flow cytometer.
eBioscience bead-based immunoassays follow the same principle as a sandwich immunoassay.
Basic Kits include essential core reagents and are required to successfully perform assays using combinations of Simplex Kits.
Soluble VEGF-R1 (sFLT-1) is a naturally occurring endogenous form of the VEGF-R1 and was originally found in the supernatant of human vascular endothelial cells. It is generated by differential splicing of the flt-1 gene. In vitro sVEGF-R1 is used to inhibit VEGF-A mediated signals in endothelial cells and in vivo it can be used to block physiological angiogenesis in several organs, e.g. in the ovary or in bones. Tumor cells transfected with the flt-1 gene are growth restricted in vivo because of the limitation in developing tumor blood vessels via VEGF-A signalling.
Characterization of angiogenic activity, such as embryonic development, placental vascularization, cancer and wound healing is measured by comparing the ratio of angiogenic stimulators (e.g. FGF-2, FGF-1, VEGF-A, Ang-1) to angiogenic inhibitors (e.g. sFLT-1, angiostatin, endostatin, thrombospondin).
