An NRP-1-binding heptapeptide whose target was initially mistaken as VEGFR2/KDR/Flk-1 due to its binding activity to a CHO-KDR culture that was later shown to express primarily NRP-1 and little KDR. V1/A7R specifically competes against VEGF₁₆₅ binding to recombinant NRP-1 in cell-free binding assays (IC₅₀ = 60 µM), while exhibiting no activity against the interaction between NRP-1 and heparin or VEGF₁₆₅ binding to KDR, VEGFR1/Flt-1, and heparin. V1/A7R is demonstrated to inhibit VEGF-dependent angiogenesis activity in HMVEC (IC₅₀ = 0.3 µM) and HUVEC cultures in vitro, as well as in a rabbit corneal neovascularization model and in mice bearing MDA-MB-231-derived tumor in vivo.，官网链接：https://www.sigmaaldrich.cn/product/mm/676495 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
