小分子滴蛋白,比例10:1,浓度蛋白0.1,小分子可以1mM。一般小分子滴大分子,小分子100uM的话,大分子就是10uM。小分子(100uL)滴定大分子(500uL)一次的体积,另外单独需要1mL缓冲液加参比池和润洗样品池、针头。尽量b证蛋白和小分子溶剂一致。
吸收热量一般在多大值合适:吸收热量没有多大合适,太低了会没有办法模拟曲线。也没有多大合适,因为不同的反应类型热量差异很大。
滴定速度是否能快一点:一般滴一滴就要10秒左右,常规滴19滴。19滴z快也要3分多,而且中间不一定平稳,不建议滴定快的。
ITC测试软件:MicroCal iTC200 (GE Healthcare, USA)。
常规测试的条件以及仪器型号:ITC experiments were performed using a MicroCal iTC200 (GE
Healthcare, USA). The reference power was set to 1.2 µcal/s, and the stirring
speed was 500rpm. A series of 19 injections of 2 µL was performed at 180-s
intervals at 25 °C. Parallel control experiments were performed. Data were
analysed using MicroCal-enabled Origin software (OriginLab, USA).
