ConjugationUnconjugated
ImmunogenOptimized DNA sequence encoding mature chain of Human B7-H4 (PHE29-ALA258) including a C-terminal His tag was expressed in HEK293 cells. NA
General Information
| Short Description | Recombinant-Human B7-H4-protein was developed from hek293. For use in research applications. |
| Host | HEK293 |
| Note | STRICTLY FOR FURTHER RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
Product Properties
| Conjugation | Unconjugated |
| Dilution Range | Spin the vial and reconstite in distilled water to a concentration not less than 0.1 mg/mL. This can then be diluted into other buffers. |
| Formulation | Lyophilised from 0.2 Mu m filtered PBS solution, pH7.2, 5% Trehalose. |
| Storage Instruction | Can be stored in working aliquots at 2°C-8°C C for one month, or at-20°C to-70°C for 1 year. Avoid repeated freeze/thaw cycles. NA |
| Endotoxin | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg (1EU/µg). NA |
| Immunoreactivity | The activity was tested by the ability to inhibit anti-CD3 antibody induced IL-2 secretion in human T lymphocytes. The calculated ED50 is < 0.7 ug/ml NA |

Additional Info
| Tissue Specificity | Overexpressed in breast, ovarian, endometrial, renal cell (RCC) and non-small-cell lung cancers (NSCLC). Expressed on activated T- and B-cells, monocytes and dendritic cells, but not expressed in most normal tissues (at protein level). Widely expressed, including in kidney, liver, lung, ovary, placenta, spleen and testis. |
| Post Translational Modifications | N-glycosylated. |
| Function | Negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. Involved in promoting epithelial cell transformation. |
