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。
重组蛋白产品该如何保存?
1) 存储条件:重组蛋白产品收到后,如不立即使用,应当保存在 -20℃ 至 -80℃ 的条件下。冻干粉可稳定保存 12 个月以上,液体类产品在 -80℃ 条件下可保存 6-12 个月。已复溶的重组蛋白样品需尽快用完,如果不能在一周内用完,需在 -20℃ 至 -80℃ 保存,可保存 3 个月以上\n2) 避免反复融冻:重组蛋白产品应注意避免反复冻融,建议将重组蛋白产品分装成多份。分装冻存时,建议选择含有一定浓度载体蛋白的溶液或培养基复溶产品。产品浓度不低于 100 ug/mL,且每管的体积不小于 20 uL。
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。
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?
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。

内毒素Please contact us for more information.
缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing 50 mM Tris, pH 8.0.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
Interferon-induced 17 kDa protein (ISG15), a 15-kDa protein of unique primary amino acid sequence, functions intracellularly as a ubiquitin homolog and a cytokine that induces production of IFN-gamma and augments NK / lymphokine-activated killer cell proliferation and function. ISG15 is secreted from monocytes and lymphocytes. ISG15 is a ubiquitin-like molecule that is strongly upregulated by type I interferons as a primary response to diverse microbial and cellular stress stimuli. Alterations in the ISG15 signaling pathway have also been found in several human tumor entities. In addition to being stimulated by type I interferon, expression of ISG15 is greatly induced by viral or bacterial infection through the Janus kinase/signal transducer and activator of transcription (Jak / STAT) signaling pathway. After induction, ISG15 is secreted by monocytes, B- and T-lymphocytes, and fibroblasts. We demonstrate the novel way in which the function of the ISG15 protein is inhibited by influenza B virus, which strongly induces the ISG15 protein: a specific region of the influenza B virus NS1 protein, which includes part of its effector domain, blocks the covalent linkage of ISG15 to its target proteins both in vitro and in infected cells.
