3CLpro/3C-like Protease Protein (E166V), SARS-COV-2, Recombinant

产品编号 TMPK-01335

3CL protease, a viral cysteine proteinase, plays an important role in co-translational proteolytic processing of Coronavirus polyproteins. The 3CL protease cleaves as much as 11 sites in the replicase polyproteins and also releases the key replicative functions of polymerase and helicase. 3CLpro/3C-like Protease Protein (E166V), SARS-COV-2, Recombinant is expressed in E. coli expression system. The predicted molecular weight is 33.80 kDa and the accession number is YP_009725301.1.

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。
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。
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?
