SHP2/NAMPT-IN-1

SHP2/NAMPT-IN-1 is an orally active dual inhibitor of SHP2 and NAMPT, with IC₅₀ values of 30.5 nM and 24.4 nM, respectively. SHP2/NAMPT-IN-1 reduces NAD⁺ levels and p-ERK expression by inhibiting NAMPT. SHP2/NAMPT-IN-1 can inhibit the migration and colony formation of MDA-MB-231 cells and promote apoptosis. SHP2/NAMPT-IN-1 has anti-proliferative activity against a variety of tumor cell lines and can reverse PD-L1-mediated T-cell immunosuppression. SHP2/NAMPT-IN-1 can be used for breast cancer research.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
