| TAG |
C-Human Fc Tag |
| MOLECULAR CHARACTERIZATION |
B7-2(Leu26-Pro247) hFc(Glu99-Ala330) |
| MOLECULAR WEIGHT |
The protein has a predicted molecular mass of 51.5 kDa after removal of the signal peptide. |
| 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 |
This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms. |
