Changes in Ang1 expression due to focal cerebral ischemia.

(A) Western blot analysis with an anti-Ang1 antibody. Each group N = 5. tPA, tissue plasminogen activator; PMCAO, permanent middle cerebral artery occlusion; Ang1, angiopoietin-1. (B) Measurements with a densitometer.(A) 采用抗Ang1抗体进行蛋白质印迹法（Western blot）分析。每组样本数N=5。tPA：组织型纤溶酶原激活剂（tissue plasminogen activator）；PMCAO：永久性大脑中动脉闭塞（permanent middle cerebral artery occlusion）；Ang1：血管生成素-1（angiopoietin-1）。(B) 采用光密度计（densitometer）进行检测。
