| Species | Cynomolgus | ||||
| Protein Construction |
|
||||
| Purity | > 95% as determined by Bis-Tris PAGE | ||||
| Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||
| Biological Activity | Loaded B7-H7/HHLA2, His, Cynomolgus on Anti-His-Biosensor can bind Human CD28H, hFc Tag in BLI assay (Gator® Prime). Test result was comparable to standard batch. | ||||
| Expression System | HEK293 | ||||
| Theoretical Molecular Weight | 38.31 kDa | ||||
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 60-70 kDa based on Bis-Tris PAGE result. | ||||
| Formulation | Lyophilized from 0.22 μm 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 for 6 months at -20℃ or below. Upon reconstitution, the product should be stable for 3 months at -80℃. Avoid repeated freeze-thaw cycles. |
| Target Background | B7-H7, also known as HHLA2 (HERV-H LTR-associating 2), is a member of the B7 family of immune regulatory proteins.Through interaction with TMIGD2, costimulates T-cells in the context of TCR-mediated activation. Enhances T-cell proliferation and cytokine production via an AKT-dependent signaling cascade. |
| Synonyms | B7H7; B7-H7; HHLA2; B7 Homolog 7 |
