  • Product overview

    Abcam’s Human soluble VEGF R1 (FLT1) in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Human soluble VEGF R1 (FLT1) in cell culture supernatants, serum and plasma (EDTA).

    A VEGF R1 (FLT1) specific mouse monoclonal antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells and incubated. A biotinylated detection polyclonal antibody from goat specific for VEGF R1 (FLT1) is then added followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. TMB is then used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution The density of yellow coloration is directly proportional to the Human VEGF R1 (FLT1) amount of sample captured in plate.

  • Tested applicationsSuitable for: Sandwich ELISAmore details
  • PlatformMicroplate


  • FunctionReceptor for VEGF, VEGFB and PGF. Has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. Isoform SFlt1 may have an inhibitory role in angiogenesis.
  • Tissue specificityMostly in normal lung, but also in placenta, liver, kidney, heart and brain tissues. Specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. It is not expressed in tumor cell lines. Isoform sFlt1 is strongly expressed in placenta.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
    Contains 7 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 protein kinase domain.
  • Cellular localizationSecreted and Cell membrane.
