| Bioactivity | |
| Description | CD19 Protein, Human, Recombinant (His), Biotinylated is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 31.6 kDa and the accession number is P15391. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | P15391 |
| Construction | A DNA sequence encoding the CD19 (P15391) (Met1-Lys291) was expressed with a C-terminal polyhistidine tag. The purified protein was biotinylated in vitro. Predicted N terminal: Pro 20 |
| Protein Purity | > 90 % 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 Sterile PBS. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot. |
| 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 | CVID3, CD19 molecule, B4 |
| Research Background |
| Molecular Weight | 31.6 kDa (predicted) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months Shipping with blue ice/Shipping at ambient temperature. |
