细胞接种(10000个细胞/孔)在康宁黑色,清底的384孔板生长培养基中,并在37℃,5%CO2下培养过夜。使用Echo 555,伴随化合物在100%DMSO中连续稀释,细胞被声控给药。板被进一步培养2小时,然后抽吸培养基,每孔加入40μL lx裂解缓冲液。Greiner黑色高绑定384孔板表面覆盖上捕获抗体,然后用3%BSA封闭。接下来除去封闭层,将15微升裂解物转移到Greiner黑色高绑定384孔板,并培养2小时。用20μL PBS抽吸并清洗板后,加入检测抗体并培养2小时。用PBS抽吸并清洗板后,加入20μL of QuantaBlu荧光过氧化物酶底物并培养1小时。20μL QuantaBlu终止液被加入到板中,荧光在Envision平板阅读器352nm激发波长和460nm发射波长下读取。每个化合物被输入到合适的软件包进行曲线模拟分析而得到数据。这个数据中,IC50值通过估算具有50%效果的化合物浓度来确定。 | ||
