| Bioactivity | Human ULBP-4, hFc Tag captured on CM5 Chip via Protein A can bind Human NKG2D, His Tag with an affinity constant of 0.17 μM as determined in SPR assay (Biacore T200). |
| Description | The expressions of both RAET1E2 transcripts and protein can be found in different tumor cells and tissues. ULBP-4 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 49.12 kDa and the accession number is Q8TD07-1. |
| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-hFc |
| Accession Number | Q8TD07-1 |
| Construction | His31-Asp225 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| 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. |
