实验目的
通过对心肺组织的加药及药后的组织破碎检测,计算组织的药物代谢情况。
实验原理
通过研磨珠撞击心肺组织细胞,使其细胞膜破裂,再检测其药物残留浓度。
实验材料和器具
样品:加药后的心肺组织细胞
仪器:高通量组织研磨仪(上海净信,Tissuelyser-48)
耗材:离心管,氧化锆研磨珠(上海净信)
实验步骤
1.采集加药后的心肺组织粗样,分别放入研磨管中
2.管中加入氧化锆珠,放入研磨仪中
3.研磨参数按要求设置,程序结束即可得到需要的破碎物。
实验注意事项
1.在做定量分析时,破碎完的样品直接离心,离心后吸取上清,研磨珠和杂质沉淀于底部(弃去),检测上清药物浓度,得到更准确的药物代谢数据。
2.若后续样本需要做质谱,研磨珠材质只能选用氧化锆,否则会影响数据。
