在这项工作中,我们报告了一种新的基于表面等离子体共振(SPR)的活细胞生物传感平台,用于测量和比较血管内皮生长因子(VEGF)与血管内皮生长因子受体(VEGFR)和VEGF与贝伐单抗的结合亲和力。结果表明,与VEGFR相比,贝伐单抗与VEGF的结合率和亲和力更高。此外,该平台已被用于模拟VEGF-VEGFR血管生成开关的体内条件。使用该平台实时监测VEGFR和贝伐单抗之间对VEGF的竞争性结合。结果显示贝伐单抗显著阻断VEGF-VEGFR结合。从结果中可以看出,所提出的策略简单且高度敏感,可以直接实时测量贝伐单抗药物对活SKOV-3细胞中VEGF-VEGFR血管生成开关的疗效。
In this work, we report a novel surface plasmon resonance (SPR) based live-cell biosensing platform to measure and compare the binding affinity of vascular endothelial growth factor (VEGF) to vascular endothelial growth factor receptor (VEGFR) and VEGF to bevacizumab. Results have shown that bevacizumab binds VEGF with a higher association rate and affinity compared to VEGFR. Further, this platform has been employed to mimic the in vivo condition of the VEGF–VEGFR angiogenic switch. Competitive binding to VEGF between VEGFR and bevacizumab was monitored in real-time using this platform. Results demonstrated a significant blockage of VEGF–VEGFR binding by bevacizumab. From the results, it is evident that the proposed strategy is simple and highly sensitive for the direct and real-time measurements of bevacizumab drug efficacy to the VEGF–VEGFR angiogenic switch in living SKOV-3 cells.
