SARS-CoV-2 NSP8 重组蛋白

SARS-CoV-2 NSP8 Protein

产品编号 TMPY-06416

NSP8 is a nonstructural protein of coronavirus. NSP8 acts as a primase in RNA synthesis. NSP8 and NSP7 are essential co-factors of NSP12 (the catalytic subunit with RNA-dependent RNA polymerase activity) that can remarkably stimulate RdRp activity. The nsp12-nsp7-nsp8 subcomplex is defined as the minimal core component for mediating coronavirus RNA synthesis. SARS-CoV-2 NSP8 Protein is expressed in E. coli expression system. The predicted molecular weight is 22.04 kDa and the accession number is YP_009725304.1.

常见问题解答

问产品的溶解度是多少？

答建议您先查询TargetMol官网、陶术官网，看该抑制剂的产品介绍，找到溶解度信息。如果没有相应信息，建议联系技术对该化合物的溶解度进行测定。

问如果低于说明书给出的最高溶解度情况下，产品仍未溶解怎么办？

答建议您使用一些辅助溶解方法，如水浴加热至 45℃ 或用超声震荡，加速粉末溶解。

问Tween-20 可以用 Tween-80 替代吗？

答不建议使用 Tween-20。相较于 Tween-20，Tween-80 的耐受性更好，Tween-80已被用作评估实验药物和毒物的行为影响的工具，且没有明显的副作用。参考文献：Castro CA， Hogan JB， Benson KA， Shehata CW， Landauer MR. Behavioral effects of vehicles: DMSO， ethanol， Tween-20， Tween-80， and emulphor-620. Pharmacol Biochem Behav. 1995 Apr;50(4):521-6.

问抑制剂是否需要灭菌？

答如果您使用 DMSO 配制：不建议灭菌，DMSO 本身具有极强的杀菌力，配制好的溶液就是无菌溶液。如果您确实担心的，可以放置 4℃ 冰箱过夜放置即可；依然有顾虑的话，需用有机系专用滤膜过滤。如果您使用水配制：可以用 0.22 μm 滤膜过滤灭菌。

问抑制剂是否可以高温灭菌？

答大部分产品均通过化学方法合成，反应条件一般在 50-80℃ 之间，因此不建议使用高温灭菌法进行灭菌，建议用 0.22 μm 滤膜过滤灭菌。

缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing 50 mM Tris, 500 mM NaCl, 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.
