Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||
Biological Activity | Measured by its binding ability in a functional ELISA. Immobilized Human B7H7, His Tag at 5μg/ml (100μl/well) on the plate can bind CD28H/IGPR-1 hFc Chimera, Human. 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 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 | 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. |
