实验操作小课堂
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。
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。
超声应使用什么仪器?
建议使用“超声清洗仪”,不推荐用“超声破碎仪”。
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。
抑制剂母液的储存方式?
母液配置完成后,一般储存于 -80℃,可以存 1 年以上。建议多分装几管,避免反复冻融,常用的存于 4 度,可放一周以上。

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
C-reactive protein (CRP) is synthesized by the liver in response to factors released by fat cells. It is a member of the pentraxin family of proteins. The levels of CRP rise in response to inflammation. Human C-reactive protein (CRP) is the classical acute phase reactant, the circulating concentration of which rises rapidly and extensively in a cytokine-mediated response to tissue injury, infection and inflammation. Serum CRP values are routinely measured, empirically, to detect and monitor many human diseases. However, CRP is likely to have important host defence, scavenging and metabolic functions through its capacity for calcium-dependent binding to exogenous and autologous molecules containing phosphocholine (PC) and then activating the classical complement pathway. CRP may also have pathogenic effects and the recent discovery of a prognostic association between increased CRP production and coronary atherothrombotic events is of particular interest.
