体内实验级重组抗小鼠PLVAP/PV-1单克隆抗体(克隆号MECA-32) 是一种针对小鼠质膜微囊相关蛋白(PLVAP,又称 PV-1)的特异性阻断与血管内皮标记抗体。PLVAP/PV-1 作为特异性表达于血管内皮细胞(特别是有孔内皮、微血管及肿瘤新生血管内皮)的单次跨膜糖蛋白,在调控内皮微囊隔膜形成、血管通透性、血脑屏障完整性以及白细胞跨内皮迁移中扮演核心角色。克隆号 MECA-32 单克隆抗体能够高亲和力结合小鼠 PLVAP 蛋白,是当前肿瘤血管生成(angiogenesis)、炎症性血管渗漏及内皮屏障损伤研究中识别与干预血管内皮的关键工具抗体。
体内实验级重组抗小鼠PLVAP/PV-1单克隆抗体(克隆号MECA-32),大鼠 IgG2a Kappa 采用基因工程技术由哺乳动物细胞重组表达,结合大鼠 IgG2a Kappa 恒定区骨架,具有优异的批间一致性与高纯度特性。产品严格把控体内实验质量标准,具备超低内毒素(<1.0 EU/mg)、无防腐剂及无载体蛋白等特点,能有效避免内毒素引发的非特异性全身炎症反应。该抗体极适合用于动物体内(in vivo)血管靶向给药、内皮功能阻断及病理模型构建,并可配套大鼠 IgG2a 同型对照抗体开展严谨的对照实验。

“Primary antibodies were rat anti-mouse CD11b, Ly6C, Ly6G and MECA-32 (BioXCell, NH); rabbit anti-mouse Lyve-1 and Prox1 (Angiobio); mouse anti-human HLA (ATCC); and PE-rabbit anti-mouse Ly6C (BD Bioscience). …Blood vascular density (BVD) and lymphatic vessel density (LVD) were determined from four images per slide captured at ×200 magnification in tumor sections stained with either anti-MECA-32 or anti-Lyve-1 antibodies (3 mice/group). …Vascular structures were enumerated using ImageJ. BVD is presented as the mean number of vessels per field ± SEM, and LVD is the mean number of Lyve-1+ structures normalized per mm2 of the section area ± SEM. …Tumor sections were double-stained with anti-human HLA and anti-mouse MECA-32 or Lyve-1 antibodies as described above. Blood and lymphatic vessels with open lumens were identified and enumerated in each section. …BVD was determined in tumors collected on the 21st day posttreatment using antibody against MECA-32 (E).”
