DELIVERY |
In Stock |
UNIPROT ID |
P0DTC2 |
EXPRESSION HOST |
HEK293 |
TAG |
C-Human Fc Tag |
MOLECULAR CHARACTERIZATION |
S1 protein NTD(Ser13-Leu303) hFc(Glu99-Ala330) |
MOLECULAR WEIGHT |
The protein has a predicted molecular mass of 59.0 kDa after removal of the signal peptide. The apparent molecular mass of S1-NTD-hFc is approximately 70-100 kDa due to glycosylation. |
PURITY |
The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. |
FORMULATION & RECONSTITUTION |
Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution. |
STORAGE & SHIPPING |
Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature. |
BACKGROUND |
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. |
