常见问题解答
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。
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。
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。

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
Tumor necrosis factor alpha (TNF-alpha), also known as TNF, TNFA or TNFSF2, is the prototypic cytokine of the TNF superfamily, and is a multifunctional molecule involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. Two receptors, TNF-R1 (TNF receptor type 1; CD120a; p55/60) and TNF-R2 (TNF receptor type 2; CD120b; p75/80), bind to TNF-alpha. TNF-alpha protein is produced mainly by macrophages, and large amounts of this cytokine are released in response to lipopolysaccharide, other bacterial products, and Interleukin-1 (IL-1). TNF-alpha is involved in fighting against the tumorigenesis, thus, is regarded as a molecular insight in cancer treatment.TNF-alpha Protein & AntibodyCancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
