In Vitro

Osemitamab (30 μg/mL, 72 h) upregulates the PD-L1 expression CLDN18.2-expressing GC cells^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Osemitamab (i.p., twice a week) exhibits signifivantly higher tumor growth inhibition when combined with Atezolizumab (HY-P9904) compared to single agents in CLDN18.2+/PD-L1+ mouse syngeneic models ^[3].

Help & FAQs

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.
