这些敏感策略可用于评估化学抑制剂的抑制作用,并结合CRISPR-Cas9基因缺失来研究药物靶点。寄生虫生长可以随着时间的推移进行监测,而不是使用端点分析来监测,以便使用敏感的报告蛋白计算寄生虫加倍的时间。这种测定有可能在384或1,536孔微孔板中进行扩展,用于测试多种化合物或以高通量方式筛选库。
这一策略可以修改,以量化其他细胞内微生物病原体的生长及其对感兴趣的药物的反应。要进行基于荧光酶的弓形虫生长测定,首先从人类食金成纤维细胞的预种96孔微孔培养物中小心地吸出介质,然后以

Summary
本文介绍的是一种协议,用于使用基于荧光酶的生长测定来评估化合物对弓形体淋酸体内生长的抑制作用。该技术用于通过基因删除相应的靶基因来确认抑制特异性。以LHVS对TgCPL蛋白酶的抑制为例。
