产品名称:2019 nCOV Spike S Trimer Protein

背景说明: 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.

别名: S protein,Spike glycoprotein,S glycoprotein,COVID-19

Accession: QHD43416.1

序列: Val16-Glu1188

种属: SARS-CoV-2

来源: 2019-nCoV Spike S is expressed from mammalian with a His tag and Avi at the C-terminal.;It contains Val16-Glu1188.

分子量: The protein has a predicted MW of 136.6 kDa. Due to glycosylation, the protein migrates to 175-230KDa based on Bis-Tris PAGE result.
