AUNP-12
AUNP-12 is highly effective in antagonizing PD-1 signaling, with desirable in vivo exposure upon subcutaneous dosing. It inhibits tumor growth and metastasis in preclinical models of cancer and is well tolerated with no overt toxicity at any of the tested doses.

Group: Enzymes. Synonyms: AuaH. Enzyme Commission Number: EC 1.1.1.394. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0314; aurachin B dehydrogenase; EC 1.1.1.394; AuaH. Cat No: EXWM-0314.
