A number of ELISA Kits are available that target VEGF Receptor 1, an alias of the protein, fms related tyrosine kinase 1. The human protein, encoded by the gene FLT1, is an enzyme and member of the Protein kinase superfamily, Tyr protein kinase family, CSF-1/PDGF receptor subfamily. The protein's cellular localization is indicated to be cytoplasmic, membrane-associated and secreted. Additional synonyms or past names for this protein may include: FLT, FLT-1, VEGFR-1, VEGFR1. Homology is conserved in other species, such as Mouse, Rat.
