Product Introduction
Bioactivity
Chemical Properties
Storage & Solubility Information
| Bioactivity | Measured by its binding ability in a functional ELISA. Immobilized mouse SIRPA-His at 10 μg/ml (100 μl/well) can bind human CD47-Fc , The EC50 of human CD47-Fc is 0.05-0.13 μg/ml.  |
| Description | SIRP alpha Protein, Mouse, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 39.4 kDa and the accession number is BAA20376.1. |
| Species | Mouse |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | BAA20376.1 |
| Construction | A DNA sequence encoding the extracellular domain of mouse SIRPA (BAA20376.1) (Met1-Asn373) was expressed with a C-terminal polyhistidine tag. Predicted N terminal: Thr 32 |
| Protein Purity | ≥ 95 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.   |
| 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 | 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 | SIRP α, SIRP, signal-regulatory protein α, signal-regulatory protein alpha, SHPS-1, Ptpns1, P84, CD172a, Bit, AI835480 |
| Research Background |
| Molecular Weight | 39.4 kDa (predicted); 50-70 kDa (reducing condition, due to glycosylation) |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
