实验操作小课堂
常见问题解答
抑制剂能否用于细胞实验?
可以的,我们的抑制剂都可以用于细胞/体外实验。但有些化合物还没有用于细胞实验的文献,这种情况下,建议您先做预实验,确保研究的可行性。
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。
如果低于说明书给出的最高溶解度情况下,产品仍未溶解怎么办?
建议您使用一些辅助溶解方法,如水浴加热至 45℃ 或用超声震荡,加速粉末溶解。
收到产品发现冰盒都化了,怎么办?
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。
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。

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
CD40, also known as TNFRSF5, is a member of the TNF receptor superfamily which are single transmembrane-spanning glycoproteins. CD40 protein plays an essential role in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. CD40 protein is expressed in B cells, dendritic cells, macrophages, endothelial cells, and several tumor cell lines. Defects in CD40 result in hyper-IgM immunodeficiency type 3 (HIGM3). In addition, CD40/CD40L interaction is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis.Cancer ImmunotherapyCo-stimulatory Immune Checkpoint TargetsImmune CheckpointImmune Checkpoint Detection: AntibodiesImmune Checkpoint Detection: ELISA AntibodiesImmune Checkpoint Detection: FCM AntibodiesImmune Checkpoint Detection: ICC AntibodiesImmune Checkpoint Detection: IP AntibodiesImmune Checkpoint Detection: WB AntibodiesImmune Checkpoint ProteinsImmune Checkpoint TargetsImmunotherapyTargeted Therapy
