The Identification and Analysis of the Spike Protein of the SARS Coro navirus

The spike(S) protein sequen ce of the SARS coronavirus was fir stly identified at the protein level .The S protein of the SARS coronav irus was purified and identified b y using proteomics technology.SDS- PAGE results showed that the molec ular weight of the S protein of th e SARS coronavirus is about 150kD. The LC MS/MS result showed the hig h consistence between the peptide fragment sequences and the sequenc es of predicted S protein of the S ARS coronavirus.
