Measurement of free and complexed soluble vascular endothelial growth factor receptor, Flt-1, in fluid samples: development and application of two new immunoassays
Vascular endothelial growth factor (VEGF) mediates endothelial cell mitogenesis and enhances vascular permeability. VEGF interacts with the endothelium via two membrane-spanning receptors, fms-like tyrosine kinase (Flt)-1 and kinase domain receptor. A soluble form of Flt-1 (sFlt-1) was isolated from endothelial cell media; however, its biological significance is still unknown, with limited data on plasma sFlt-1 levels in disease states. We have developed two new ELISAs for detecting free and VEGF-complexed sFlt-1, which were tested in accordance with standard validation and assessment methodologies employed in commercial settings. The intra-and inter-assay coefficients of variation are <5% and 10% respectively, and results are highly reproducible. Applying these ELISAs in a clinical setting, we measured levels of VEGF, free and complexed sFlt-1 in citrated plasma from 40 patients with cardiovascular disease and 40 healthy controls. Median (interquartile range) plasma levels of VEGF in
