Recombinant human RAS (GTPase), isoform b, encompassing amino acids 2-185. This construct contains an N-terminal His-tag (6xHis). The protein also contains mutation of interest G12V. The protein (Biohippo #100480) was affinity purified and loaded with GppNHp, a non-hydrolyzable GTP analog. Unbound GppNHp was removed by spin column. Constructs: KRAS (G12V) (His-2-185) - (GppNHp)
