SARS-COV-2 Spike S1 Protein (hFc & Avi)

产品编号 TMPK-00432

The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity. SARS-COV-2 Spike S1 Protein (hFc & Avi) is expressed in HEK293 mammalian cells with C-hFc-Avi tag. The predicted molecular weight is 102.6 kDa and the accession number is A0A6G7K2L4.

种属	SARS-CoV-2
表达系统	HEK293 Cells
标签	C-hFc-Avi
蛋白编号	A0A6G7K2L4
别名	Spike,S1 protein,Spike protein S1,S1 protein,S glycoprotein Subunit1
蛋白构建	Gln14-Arg683
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	102.6 kDa (predicted). Due to glycosylation, the protein migrates to 130-140 kDa based on Tris-Bis PAGE result.
内毒素	< 1 EU/μg by the LAL method.
缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
复溶方法	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
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.
