  • 实验小鼠心脏灌注固定：解剖学研究组织标本制备

    Version 3

    Adult mice are anesthetized by intraperitoneal injection of ketamine (150 mg/kg) with xylazine (15 mg/kg); the chest is opened and a needle connected to a peristaltic pump is placed in the left ventricle, and a prewash solution followed by 4% paraformaldehyde in 0.1 M phosphate buffer (pH 7.4) is perfused. A step in the flow labels the arterial and capillary systems in vivo with DyLight 649-conjugated tomato lectin injected into the left ventricle. Dissected tissues are post-fixed at 4 °C for 18–24 h, washed in 0.1 M PBS (pH 7.2) and stored at 4 °C in PBS containing 0.1% sodium azide until used for immunohistochemistry or other microscopic analysis, yielding well-preserved tissue for anatomical studies. Institutional animal ethics approval must be obtained before performing this procedure.
