In Vivo

S-570 (1-30 mg/kg; p.o.) effectively attenuates systemic inflammation in a CMA-stimulated mouse model by significantly suppressing IFN-β, IL-6, and TNF-α production in a dose-dependent manner^[1].

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.
