常见问题解答
化合物如何用于动物实验?如何确立剂量、给药方式等?
同一个化合物对不同动物模型、不同疾病模型的用法不一样,建议根据实验目的,查询文献选择用法。 常见的给药方式包括腹腔注射、灌胃等。由于首过效应,一般可以灌胃的也可以腹腔注射,可以腹腔注射的不一定适合灌胃。不同种属的给药剂量可以根据官网的表格换算。但仅供参考,实际应用中可能未必合适或者准确,尽量以具体某种动物给药剂量的参考文献为主。 我们的化合物都可以进行细胞动物实验,但有些化合物还没有用于动物实验的文献,这种情况下,您可以尝试进行动物实验,但我们无法提供使用方式,也无法保证药效。
抑制剂是否可以高温灭菌?
大部分产品均通过化学方法合成,反应条件一般在 50-80℃ 之间,因此不建议使用高温灭菌法进行灭菌,建议用 0.22 μm 滤膜过滤灭菌。
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。
是否能直接用缓冲液对抑制剂 DMSO 母液做梯度稀释?
大部分情况下,都是可以溶解的。但有时,有机试剂直接加入水相介质时会析出。建议将抑制剂先以DMSO做梯度稀释,再将经过稀释的抑制剂加入缓冲液或细胞培养基。有些抑制剂甚至只有在其工作浓度下才能溶于水相。 比如细胞实验中希望终浓度为 1 μM 的话,可以把 10 mM 的 DMSO 母液用 DMSO 稀释到 1 mM,再吸 2 μL 加入到 2 mL 的生理盐水/PBS/细胞培液,终浓度即为 1 μM。 为避免药物析出,稀释前,可将母液和培养基 37℃ 预热,避免温度低造成严重析出。若稀释过程中出现化合物析出的情况,建议您采用超声加热的方法使其复溶。
细胞实验中,抑制剂如何溶解?
用 DMSO 配置较高浓度母液,母液存于 -80℃,建议多分装几管,一周内使用的存于 4℃,避免反复冻融。实验时用 pbs、生理盐水、培养基、水这些稀释,细胞实验DMSO的终浓度不超过 0.1%。如果超过 0.1%,则需要在做预试验的时候,先进行溶剂阴性对照实验,排除溶剂对细胞的影响。

缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
复溶方法
A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
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.
研究背景
The fourth gene of the EBOV genome encodes a 16-kDa envelope-attached glycoprotein (GP) and a 11 kDa secreted glycoprotein (sGP). Both GP and sGP have an identical 295-residue N-terminus, however, they have different C-terminal sequences. Recently, great attention has been paid to GP for vaccines design and entry inhibitors isolation. GP is a class I fusion protein which assembles as trimers on viral surface and plays an important role in virus entry and attachment. Mature GP is a disulfide-linked heterodimer formed by two subunits, GP1 and GP2, which are generated from the proteolytical process of GP precursor (pre-GP) by cellular furin during virus assembly . The GP1 subunit contains a mucin domain and a receptor-binding domain (RBD); the GP2 subunit has a fusion peptide, a helical heptad-repeat (HR) region, a transmembrane (TM) domain, and a 4-residue cytoplasmic tail. The RBD of GP1 mediates the interaction of EBOV with cellular receptor (e.g. DC-SIGN/LSIGN, TIM-1, hMGL, NPC1, β-integrins, folate receptor-α, and Tyro3 family receptors), of which TIM1 and NPC1 are essential for EBOV entry; the mucin domain having N- and O-linked glycans enhances the viral attachment to cellular hMGL, and participates in shielding key neutralization epitopes, which helps the virus evades immune elimination. There are large conformation changes of GP2 during membrane fusion, which enhance the insertion of fusion loop into cellular membrane and facilitate the release of viral nucleocapsid core to cytoplasm.
