常见问题解答
收到化合物后,是否需要称量后配制储备液?
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。
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。
抑制剂能否用于动物实验?
可以的,我们的抑制剂都可以用于动物/体内实验。但有些化合物还没有用于动物实验的文献,这种情况下,建议您先做预实验,确保研究的可行性。
小规格产品,收到瓶子后看不到任何东西?
由于产品规格小,粉末在运输过程中产生的静电导致过于分散,管壁和盖子上皆会粘着,您可以放心,离心后加入适量溶剂直接配制母液、充分溶解即可。
抑制剂是否需要灭菌?
如果您使用 DMSO 配制:不建议灭菌,DMSO 本身具有极强的杀菌力,配制好的溶液就是无菌溶液。如果您确实担心的,可以放置 4℃ 冰箱过夜放置即可;依然有顾虑的话,需用有机系专用滤膜过滤。 如果您使用水配制:可以用 0.22 μm 滤膜过滤灭菌。

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. Solutions are shipping with dry ice.
研究背景
Human Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) is a secretory subtilase belonging to the proteinase K subfamily. PCSK9 is synthesized as a soluble zymogen that undergoes autocatalytic intramolecular processing in the ER , the pro domain and mature chain secrete together through noncovalent interactions. PCSK9 binds with low-density lipoprotein receptor (LDLR) and plays a major regulatory role in cholesterol homeostasis. Inhibition of PCSK9 function by preventing PCSK9/LDLR interaction is currently being explored as a means of lowering cholesterol levels. PCSK9 also binds to apolipoprotein receptor 2 (ApoER2), and play a role in the neural development.
