常见问题解答
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。
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。
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。
为什么某些重组蛋白溶液中还需要添加载体蛋白?
载体蛋白通常被用于提高蛋白的稳定性,防止蛋白在冷冻或解冻过程中粘附在管壁上。塑料管对蛋白有一定的吸附能力,这可能导致蛋白和管壁之间难以分离,导致溶液中蛋白的实际浓度下降,从而影响其活性。为减少这种损失,在长期保存重组蛋白 产品之前,建议添加常用的载体蛋白溶液,例如0.1% BSA(牛血清白蛋白)、5% HSA(人血清白蛋白)、10% FBS(胎牛血清)或 5% 海藻糖等。如果重组蛋白的浓度较低,强烈建议添加适量的载体蛋白。
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。

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 cluster of differentiation (CD) system is commonly used as cell markers in Immunophenotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. Cluster of differentiation 24, also known as signal transducer CD24 or heat stable antigen CD24 (HSA), is a mucin-type glycosylphosphatidylinositol-linked glycoprotein expressed on the surface of B-cells, differentiating neuroblasts and many tumors. It is involved in molecular adhesion and metastatic tumor spread and serve as a normal receptor for P-selectin. The CD24 / P-selectin pathway could be important in disseminating tumor cells by facilitating the interaction with platelet and endothelial cells. It has also been considered as a tumor marker. High rate of CD24 expressions have been found in epithelial ovarian cancer, breast cancer, non-small cell lung cancer, prostate cancer and pancreatic cancer.
