| Antigen | Recombinant human Tie-2 protein (23-745 aa, EC domain) was expressed in NSO cells as His-tagged Fc (IgG1) protein Chimera (~100 kda) and purified (>90%). Recombinant chimeric Tie-2 protein migrates as ~165 kda under reducing conditions.
Endotoxin concentration is <0.1 ng/1 ug of the protein. Biological activity is not established. |
