表达区间及表达系统（Source）	SARS-COV-2 NSP7&NSP8 Protein is expressed from E.coil with His tag at the C-Terminus. It contains Ser1-Gln83(NSP7)&Ala1-Gln198(NSP8) [Accession \| YP_009725303.1(NSP7)&YP_009725304.1(NSP8)].
分子量大小（Molecular Weight）	The protein has a predicted MW of 32.8 kDa same as Bis-Tris PAGE result.
纯度（Purity）	> 95% as determined by Bis-Tris PAGE
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
制剂（Formulation）	Lyophilized from 0.22μm filtered solution in 20mM Tris, 150mM Nacl, 200mM Arginine (pH 8.2). Normally 8% trehalose is added as protectant before lyophilization.
重构方法（Reconstitution）	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
存储（Storage）	-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
