| 描述: “Recombinant SARS-CoV-2 RBD(L452R |
| 背景: 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. |
| 物种/宿主: HEK293 |
| 分子量: The protein has a predicted molecular mass of 51.2 kDa after removal of the signal peptide.The apparent molecular mass of RBD(L452Rand T487K)-hFc is approximately 55-70 kDa due to glycosylation. |
| 分子特征: S protein RBD(L452Rand T487K)(Arg319-Phe541) hFc(Glu99-Ala330) |
| 纯化: The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. |
| Formulation & Reconstitution: Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% – 8% trehalose is added as protectants before lyophilization. |
| 储存和运输: 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. |
