常见问题解答
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。
期货产品没有纯度啊?这个纯度在哪里看
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。
细胞实验中需要加多少抑制剂?
通常建议您参考同模型实验发表的文献报道;除参考文献报道以外,还需要通过预实验做“剂量-效应曲线”确定最佳作用浓度(浓度梯度);通过“时间-效应曲线”确定最佳孵育时间(处理时间梯度)。另外,抑制剂的使用量受多种因素影响,包括抑制对象的可接触性、细胞通透性、孵育时间、细胞种类等等。我们建议通过检索文献确定使用抑制剂的起始浓度。 如果有报道的 Ki 值或 IC50 值,可以采用其 5-10 倍的量开始尝试以达到抑制酶活性的最佳效果。 如果抑制剂的 Ki 值或 IC50 值未知,则需要在更广泛的范围尝试抑制剂的使用浓度,并采用 Michaelis-Menten 动力学计算 Ki 值。 一般设立溶解抑制剂时所采用的溶剂作为对照,以排除溶剂的非特异性影响。
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。
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。

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
ERP72, also known as PDIA4, is an endoplasmic reticulum luminal protein which belongs to the protein disulfide isomerase family. ERP72 is a stress protein and participates in the catalysis of protein-S-S-bond rearrangement. Both PDIA4 and PDIA3 function as proteases, protein disulfide isomerases, phospholipases or an arrangement of these. ERP72 compose part of a large chaperone multiprotein complex comprising CABP1, DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA4, PPIB, SDF2L1, UGT1A1 and very small amounts of ERP29, but not, or at very low levels, CALR nor CANX.
