常见问题解答
细胞实验中需要加多少抑制剂?
通常建议您参考同模型实验发表的文献报道;除参考文献报道以外,还需要通过预实验做“剂量-效应曲线”确定最佳作用浓度(浓度梯度);通过“时间-效应曲线”确定最佳孵育时间(处理时间梯度)。另外,抑制剂的使用量受多种因素影响,包括抑制对象的可接触性、细胞通透性、孵育时间、细胞种类等等。我们建议通过检索文献确定使用抑制剂的起始浓度。 如果有报道的 Ki 值或 IC50 值,可以采用其 5-10 倍的量开始尝试以达到抑制酶活性的最佳效果。 如果抑制剂的 Ki 值或 IC50 值未知,则需要在更广泛的范围尝试抑制剂的使用浓度,并采用 Michaelis-Menten 动力学计算 Ki 值。 一般设立溶解抑制剂时所采用的溶剂作为对照,以排除溶剂的非特异性影响。
超声应使用什么仪器?
建议使用“超声清洗仪”,不推荐用“超声破碎仪”。
超声应使用什么样的频率?
频率建议使用常规的超声清洗频率即可,一般在20 kHz - 100 kHz。
母液配置的计算方法?
(1) c=n/v=m/M/v 浓度=物质的量/体积=质量/相对分子质量/体积 (2) 官网产品详情页下方有溶液配制表格,可以参考计算好的加入溶剂体积
抑制剂加 DMSO 配成母液之后,能否放在常温的环境保存1周?
不建议这么做,母液配置好分装保存,建议存于 -20℃ 或 -80℃,尽量避免反复冻融。如果您订购的规格很大,可以考虑分装粉末保存,固体粉末是比较稳定的,-20℃ 可以保存三年。
