Human RalB is supplied as a recombinant biotinylated small GTPase in a 0.1 mg format. RalB is a member of the Ral branch of the RAS superfamily and is useful for studying downstream signaling effector engagement and small GTPase pathway biology. Applications include SPR, BLI, pull-down, AlphaScreen, RAL-family GTPase signaling studies, GEF interaction assays, small molecule screening. Site-specific N-terminal biotinylation enables direct immobilization on streptavidin surfaces for interaction and screening workflows.
