| Bioactivity | |
| Description | CD28 Protein, Mouse, Recombinant (His), Biotinylated is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 16.5 kDa and the accession number is P31041. |
| Species | Mouse |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | P31041 |
| Construction | A DNA sequence encoding the extracellular domain (Met 1-Lys 149) of mouse CD28 (NP_031668.3) was fused with a polyhistidine tag at the C-terminus. The purified protein was biotinylated in vitro. Predicted N terminal: Cys 27 |
| Protein Purity | > 95 % as determined by SDS-PAGE |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | CD28 molecule |
| Research Background |
| Molecular Weight | 16.5 kDa (predicted); 32-35 kDa (reducing condition, due to glycosylation) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months Shipping with blue ice/Shipping at ambient temperature. |
