常见问题解答
如何将冻干的重组蛋白配置为储备液?
在打开盖⼦之前,先使用 10000-12000 rpm 的转速进行离心,20-30 秒,将附着在管盖或管壁上的冻⼲粉收集到管底,以避免损失。大多数蛋白可通过加入无菌蒸馏水来重新溶解。如果需要除水以外的其他稀释剂,产品 COA 中会对其进行说明。一般储备液浓度建议不要低于 100 μg/mL,分装储存避免反复冻融。
重组蛋白产品是如何运输的?
大部分重组蛋白产品为冻⼲粉,对温度不敏感,在室温下稳定,一般室温或蓝冰运输。对于液体类蛋白,一般采用⼲冰运输。如果您收到产品时发现冰盒已经融化,无需担心,蛋白可以正常使用,短时间内不会影响产品质量。如果特定蛋白在室温下不稳定,我们会提供相应的低温运输方式,以确保产品质量不受影响。
为什么重组蛋白的体积和质量与预期不符?
蛋白冻干粉由蛋白原液冻干而来,冻干粉质量不等同于蛋白质量。由于冻⼲产品的体积大⼩受多种因素影响,包括冻⼲前缓冲液的组分、盐离⼦浓度以及产品本身的浓度等。冻⼲粉可能看上去很多,也可能肉眼不易观察到,这些都是正常现象,请您放心使用。在收到产品后,照常复溶、使用或分装储存即可。
重组蛋白有吗?
您需要什么种属的蛋白呢,对表达系统和标签有要求吗,用于什么实验?
蛋白能保证活性吗?
我们有现货的产品,有活性数据的话会展示在官网生物活性那栏,没有数据的也不代表就一定没有活性,是我们还没有建立活性检测方法,没有进行测试,但是我们的蛋白都是优先按照有活性的方法去表达纯化的。

生物活性
1. Measured by its ability to bind biotinylated Cynomolgus IL18 in functional ELISA. 2. Measured by its ability to inhibit the IL-18-induced response of KG‑1 human acute myelogenous leukemia cells. The ED50 for this effect is 0.05-0.35μg/mL in the presence of 50 ng/mL of recombinant human IL-18.

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
Interleukin-18-binding protein (IL-18BP) is a constitutively expressed and secreted protein. IL-18BP is a cytokine receptor that belongs to the interleukin 1 receptor family. This receptor specifically binds interleukin 18 (IL18) and is essential for IL18 mediated signal transduction. IFN-alpha and IL12 are reported to induce the expression of this receptor in NK and T cells. This gene along with four other members of the interleukin 1 receptor family, including IL1R2, IL1R1, ILRL2 (IL-1Rrp2), and IL1RL1 (T1/ST2), form a gene cluster on chromosome 2q. The adjacently located family members IL18 Receptor 1 (IL18R1) and IL18 receptor accessory protein (IL18RAP) may also be important in the development of asthma and atopy. IL-18 binding protein (IL-18BP) was only moderately elevated, resulting in a high level of biologically active free IL-18 in HPS. A severe IL-18/IL-18BP imbalance results in Th-1 lymphocyte and macrophage activation, which escapes control by NK-cell cytotoxicity and may allow for secondary HPS in patients with underlying diseases.
