| Bioactivity | Recombinant Human IGSF11 Protein (ECD, Fc Tag) captured on CM5 chip via Anti-Human IgG Fc, can bind Recombinant Human B7-H5 Protein (His Tag) with an affinity constant of 30.800 μM as determined in an SPR assay (Biacore 8K) (Routinely tested). |
| Description | VISTA Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 19.6 kDa and the accession number is AAH20568.1. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-His |
| Accession Number | AAH20568.1 |
| Construction | A DNA sequence encoding the human Gi24 (AAH20568.1) (Met1-Ala194) was expressed with a polyhistidine tag at the C-terminus. Predicted N terminal: Phe 33 |
| 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. |
