商品介绍
Specifications
| SPECIES: | Human |
|---|---|
| SOURCE SPECIES: | CHO cells |
| SEQUENCE: | The extracellular domain of human B7-H4 (aa 29-258) is fused to the N-terminus of the Fc region of human IgG1. |
| FUSION TAG: | Fc Tag |
| TESTED APPLICATIONS: | |
| APPLICATIONS: | This recombinant proteins is for research use only. |
| BIOLOGICAL ACTIVITY: | Measured by the ablility to inhibit anti-CD3-induced proliferation of stimulated human T cells. Human T lymphocytes cultured for 72 hours with PHA were incubated for an additional 3 days in 96 well place coated with 500 ng/ml anti-CD3 and 10ug/ml human B7H4/Fc. The presence of human B7H4/Fc at 10ug/ml inhibited anti CD3 response by 30-50%. Optimal dilutions should be determined by each laboratory for each application. |

Background
| B7H4 is a B7 family member that negatively regulates T cell immunity by inhibiting of T cell proliferation, cytokine production, and cell cycle progression. In vitro, B7H4 inhibits CD4+ and CD8+ T cell proliferation, cytokine production, and generation of alloreactive cytotoxic T-cells (CTLs). In vivo, blockade of endogenous B7-H4 by specific monoclonal antibody promotes T cell responses. B7-H4 ia an important negative regulator of innate immunity through growth inhibition of neutrophils. B7-H4 is expressed on some tumor cancer cells. The role of B7-H4 in tumor progression may be to transform precancerous cells and then protect them from immunosurveillance. |
