常见问题解答
如何设置母液浓度?
母液浓度需低于官网给出的溶解度,在这个范围内,根据工作液浓度设置母液浓度,细胞实验中,建议母液浓度设定在工作液浓度的 1000 倍以上。
得到的杀死细胞的 IC50 与网页上 IC50 差距较大怎么办?
您所测试的IC50是指细胞的增殖抑制实验(半抑制率),细胞增殖抑制实验 IC50值,和网页上的靶点IC50其实是不同的意义。文献里和网页上 IC50其实往往是指对于靶点无细胞实验的抑制率,这样的实验一般是通过激酶或者蛋白纯化实验做出来的,nM 级别的浓度比较常见,但是细胞的增殖抑制实验 IC50 是指细胞的半致死率,同时牵涉到细胞的代谢以及渗透,一般浓度会高一些。 另外,同一个化合物对不同细胞模型的效果也是不同的,建议尝试增加孵育量、延长孵育时间。
产品溶解需要超声吗?如果没有超声仪怎么办?
超声可以加快粉末的溶解速度,如果您的化合物溶解不了,建议您尝试超声。如果您没有超声仪,建议您选择较低母液浓度,或者较少粉末量,尝试溶解。
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。
准备进行动物实验,收到大包装粉末后,如何分装溶解?
根据配制出来的溶液是不是澄清的确定一次性能配多少:如果配制出来是澄清溶液,可以一次性多配制一些,储存于4度冰箱,大概一周配一次,放久了可能会失效;如果配制出来是混悬液,建议每次使用的时候都现配现用。

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 asialoglycoprotein receptor (ASGPR), an endocytotic cell surface receptor expressed by hepatocytes, is triggered by triantennary binding to galactose residues of macromolecules such as asialoorosomucoid (ASOR). ASGPR belongs to the long-form subfamily of the C-type/Ca2+ dependent lectin family. It is a complex of two noncovalently-linked and highly homologous subunits, a major 42 kDa glycoprotein ASGPR1(MHL-1) and a minor 51 kDa glycoprotein ASGR2 (MHL-2). ASGPR1 is synthesized as a type II transmembrane protein that contains a cytosolic N-terminal domain, a single transmembrane segment, and an extracellular domain which contains two important structural regions. The first is a stalk domain that contributes to noncovalent oligomerization, and the second is a Ca2+-dependent carbohydrate binding domain at the very C-terminus that is unusually stabilized by three ions. The research regarded that ASGPR1 could be targeted for anti- hepatitis B virus (HBV) drug development.
