VEGFR-2/Flk-1 (Peptide), soluble

The antibody recognizes solely the endogenous soluble form of mouse vascular endothelial growth factor receptor 2, alos known as CD309, VEGFR2, KDR, protein tyrosine kinase receptor flk-1, and fetal liver kinase-1. The endogenous soluble mouse esFlk-1 generated by alternative splicing consists of the first 6 Ig-like loops followed by the unique C-terminal end: GMEASLGDRIAMP. Flk-1 is a member of the tyrosine protein kinase family, sub-family CSF-1/PDGF, that contains a single pass transmembrane receptor with a protein kinase domain and seven immunoglobulin-like domains in the extracellular region. Flk-1 is expressed at high levels in adult heart, lung, kidney, brain, and skeletal muscle; other tissues express at lower levels. Flk-1 is a receptor for VEGF-A or fully processed VEGF-C; ligand binding plays a key role in vascular development and vascular permeability.
