常见问题解答

问溶解度中写的“< 1 mg/mL refers to the slightly soluble or insoluble ”是什么意思？

答这句话指的是，如果溶解度 < 1 mg/mL，那我们就认为它是微溶或不溶的，这是针对写的“DMSO：Insoluble”或“DMSO：slightly soluble”这类化合物的。

问抑制剂加 DMSO 配成母液之后，能否放在常温的环境保存1周？

答不建议这么做，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。

问收到化合物后，是否需要称量后配制储备液？

答对于小包装，如 1 mg、5 mg、10 mg 等，不建议二次称量。这样会导致化合物损耗，且无法估算。TargetMol 所有产品原装进口，精准称量，您收到后可直接添加相应量溶剂。对于大包装，如果您需要分批次实验，可每次称量后配制储备液，建议您 10 mg 起称，称量的误差会小一些；当然条件允许，也可以先配制成高浓度母液，分装备用。

问细胞实验中需要加多少抑制剂？

答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。

问收到产品发现冰盒都化了，怎么办？

答一般化合物粉末对温度不敏感，加冰盒是为了防止极端气温，如果冰盒融化不影响产品质量。

内毒素	< 1 EU/μg by the LAL method.
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
复溶方法	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式	In general, Lyophilized powders are shipping with blue ice.
