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。
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?
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。

内毒素< 1.0 EU/μg of the protein as determined by the LAL method.
缓冲液Lyophilized from a solution filtered through a 0.22 μm filter, containing 100 mM Glycine, 10 mM NaCl, 50 mM Tris, pH 7.5. 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
Endothelin-converting enzyme 2, also known as ECE-2, is a metalloprotease that possesses many properties consistent with it being a neuropeptide-processing enzyme. Endothelin-converting enzymes (ECEs) are the key enzymes in the endothelin (ET) biosynthesis that catalyze the conversion of big ET, the biologically inactive precursor of mature ET. Two enzymes, termed ECE-1 and ECE-2, have been molecularly identified. ECE-2 is found primarily in neural tissues, with high levels of expression in midbrain, cerebellum, hypothalamus, frontal cortex and spinal cord and moderate levels in hippocampus and striatum. ECE-2 is strongly down-regulated in inferior parietal lobe from Alzheimer disease patients (at protein level). ECE-2 converts big endothelin-1 to endothelin-1. It is involved in the processing of various neuroendocrine peptides, including neurotensin, angiotensin I, substance P, proenkephalin-derived peptides, and prodynorphin-derived peptides. ECE-2 may limit beta-amyloid peptide accumulation in brain. It may also have methyltransferase activity. A comparison of residues around the cleavage site revealed that ECE-2 exhibits a unique cleavage site selectivity that is related to but distinct from that of ECE-1.
