常见问题解答

问如何稀释工作液？

答根据您的工作液浓度，计算母液所需要稀释的倍数和所需母液的体积。建议用水、生理盐水、PBS等溶剂进行稀释，如果是细胞实验，可以使用培养基。取适当的溶剂缓慢加入到母液中，直到达到您的工作液浓度，可以通过涡旋或者移液枪轻轻吹打帮助混匀。我们的化合物大部分是脂溶性的，所以在使用 PBS 或者培养基等稀释工作液的时候，会有沉淀析出，这些都是正常现象，大多时候可以通过超声完全溶解。工作液建议现配现用！

问母液配置的计算方法？

答（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

问超声应使用什么样的频率？

答频率建议使用常规的超声清洗频率即可，一般在20 kHz - 100 kHz。

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。

问期货产品没有纯度啊？这个纯度在哪里看

答期货产品的话，是没有纯度信息，也没有质检信息的。有了现货之后我们会进行质检，测出试剂的纯度和结构等相关信息，并且展示在官网的活性描述上方。

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 influenza viral Hemagglutinin (HA) protein is a homotrimer with a receptor binding pocket on the globular head of each monomer.HA has at least 18 different antigens. These subtypes are named H1 through H18.HA has two functions. Firstly, it allows the recognition of target vertebrate cells, accomplished through the binding to these cells' sialic acid-containing receptors. Secondly, once bound it facilitates the entry of the viral genome into the target cells by causing the fusion of the host endosomal membrane with the viral membrane. The influenza virus Hemagglutinin (HA) protein is translated in cells as a single protein, HA, or hemagglutinin precursor protein. For viral activation, hemagglutinin precursor protein (HA) must be cleaved by a trypsin-like serine endoprotease at a specific site, normally coded for by a single basic amino acid (usually arginine) between the HA1 and HA2 domains of the protein. After cleavage, the two disulfide-bonded protein domains produce the mature form of the protein subunits as a prerequisite for the conformational change necessary for fusion and hence viral infectivity.
