| Protein Construction |
|
||||
| Purity | > 95% as determined by BisTris PAGE | ||||
| Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||
| Biological Activity | Measured by its binding ability in a functional ELISA.Test result was comparable to standard batch. | ||||
| Expression System | HEK293 | ||||
| Theoretical Molecular Weight | 40.7 kDa | ||||
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 50-60 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 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 | CD28H is constitutively expressed on all naive T cells. Repetitive antigenic exposure, however, induces a complete loss of CD28H on many T cells, and CD28H negative T cells have a phenotype of terminal differentiation and senescence. After extensive screening in a receptor array, a B7-like molecule, B7 homologue 5 (B7-H5), was identified as a specific ligand for CD28H. |
