Product Information
| Description: | Ontorpacept (TTI-621) is a soluble fusion protein that consists of the human SIRPĪ± N-terminal (1-118) linked to the Fc region of human IgG1. The N-terminal (1-118)-fragment of ontorpacept is a binding domain for CD47 which is an inhibitor of phagocytosis by macrophages. Ontorpacept is a CD47-blocking checkpoint inhibitor with antitumor activity. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
