The TROP-2 protein serves as a growth factor receptor and plays a key role in mediating cellular responses related to growth regulation. This implies its importance in transducing signals that influence cell growth processes. TROP-2 Protein, Rat (246a.a, HEK293, His) is the recombinant rat-derived TROP-2 protein, expressed by HEK293 , with C-His labeled tag.
