| 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. |
| Recombinant Human CD28H/IGPR-1 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Leu23-Gly150. |

| The protein has a predicted MW of 15.1 kDa. Due to glycosylation, the protein migrates to 42-52 kDa based on the Tris-Bis PAGE result. |
| Immobilized Human CD28H, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human B7-H7, hFc Tag with the EC50 of 52.7ng/ml determined by ELISA. See testing image for detail. |

| > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Less than 1EU per ug by the LAL method. |
| Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as a protectant before lyophilization. |
| Reconstituted protein stable at -80 C for 12 months, 4 C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
| Shipped at ambient temperature. |
| Centrifuge tubes before opening. Reconstituting to a concentration of more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
