Product Summary for Human VEGFR1/Flt-1 Quantikine ELISA Kit
The Quantikine® Human VEGF R1/Flt-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human VEGF R1 in cell culture supernates, cell lysates, serum, plasma, and saliva. It contains NS0-expressed recombinant human VEGF R1 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human VEGF 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 natural human VEGF R1.

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 twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.

Background: VEGFR1/Flt-1
VEGFR1 (vascular endothelial growth factor receptor 1; Flt-1) binds to VEGF-A, VEGF-B, and PlGF and functions in vasculogenesis, angiogenesis, lymphangiogenesis, and wound healing. It is expressed on endothelial cells, osteoblasts, placental trophoblasts, renal mesangial cells, and some hematopoietic stem cells. It can heterodimerize with VEGFR2 and modulate VEGFR2 mediated endothelial cell proliferation and vessel branching. VEGFR1 engagement on monocyte/macrophage lineage cells enhances their migration, and release of growth factors and cytokines.
