Recombinant SARS-CoV-2 (2019-nCoV) S1-eiwitCTD met C-terminaal humaan Fc-tag

Expression Host : HEK293 The protein has a predicted molecular mass of 47.9 kDa after removal of the signal peptide. SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as Covid19 (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. The spike protein is a type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which accounts for recognizing the cell surface receptor, ACE2. S2 contains basic elements needed for the membrane fusion. Recent publications indicate that S1-RBD domain can induce virus neutralizing-antibody and T cell response.

S1 protein CTD, Spike protein S1 CTD, BetaCoV S1-CTD, COVID-19

The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining.

Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose is added as protectants before lyophilization.
