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

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.

种属	SARS-CoV-2
表达系统	HEK293
标签	C-hFc-Avi
蛋白编号	A0A6G7K2L4
别名	S1 protein, Spike,S1 protein, Spike protein S1, S glycoprotein Subunit1
蛋白构建	Recombinant Biotinylated SARS-COV-2 Spike S1 Protein is expressed from HEK293 with hFc tag and Avi tag at the C-Terminus. It contains Gln14-Arg683.[Accession \|QHD43416.1]
蛋白纯度	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
分子量	The protein has a predicted MW of 102.6 kDa. Due to glycosylation, the protein migrates to 130-140 kDa based on Tris-Bis PAGE result.

内毒素	Less than 1EU per μg by the LAL method.
缓冲液	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
复溶方法	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	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
运输方式	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
