生物活性

产品描述	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.
生物活性	1. Immobilized Human ACE2, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for SARS-COV-2 Spike S1, hFc Tag with the EC50 of 92.3ng/ml determined by ELISA. 2. SARS-COV-2 Spike S1, hFc Tag captured on CM5 Chip via Protein A can bind Human ACE2, His Tag with an affinity constant of 3.80 nM as determined in SPR assay.

标签	C-hFc-Avi
蛋白编号	A0A6G7K2L4
蛋白构建	Gln14-Arg683
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
蛋白性状	Lyophilized powder
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.
别名	Spike,S1 protein, Spike protein S1, S1 protein, S glycoprotein Subunit1
内毒素	< 1 EU/μg by the LAL method.

化学信息

分子量	102.6 kDa (predicted). Due to glycosylation, the protein migrates to 130-140 kDa based on Tris-Bis PAGE result.
颜色	White
物理性状	Lyophilized powder

储存&溶解度

运输方式	In general, Lyophilized powders are shipping with blue ice.
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.
