> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
||||
| Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||
| Biological Activity | Measured by its binding ability in a functional ELISA. Immobilized B7-H4 hFc Chimera, Human at 0.5μg/ml (100μl/Well) on the plate can bind Biotinylated AntiB7H4 Antibody, hFc Tag. Test result was comparable to standard batch. | ||||
| Expression System | HEK293 | ||||
| Theoretical Molecular Weight | 52.1 kDa | ||||
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 70-80 kDa based on Bis-Tris PAGE result. | ||||
| Formulation | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). | ||||
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. | ||||
| Storage & Stability | Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background | B7-H4, also known as B7x and B7S1, is a 50-80 kDa glycosylated member of the B7 family of immunomodulatory proteins.B7-H4 is up-regulated in several carcinomas in correlation with tumor progression and metastasis. A soluble form of B7-H4 is elevated in the serum of ovarian cancer, renal cell carcinoma, and rheumatoid arthritis patients, also in correlation with advanced disease status . |
| Synonyms | B7H4; B7-H4; B7S1; B7h.5; B7x; FLJ22418; VTCN1; PRO1291 |
