KRAS G12C Proteins

Shop recombinant human KRAS G12C proteins for covalent inhibitor research, binding assays, drug discovery workflows, and RAS pathway studies.

KRAS G12C Proteins

Selecting a KRAS G12C Protein for Your Assay

KRAS G12C assays often depend on nucleotide state, covalent inhibitor workflow, immobilization strategy, and downstream binding partner. Use GDP-loaded KRAS G12C for GDP-state inhibitor profiling or exchange workflows, GppNHp-loaded KRAS G12C for active-state studies, and biotinylated KRAS G12C for streptavidin-based capture assays.

Defined KRAS G12C Reagents

Select KRAS G12C proteins by nucleotide state, biotinylation format, tag placement, mutation background, and assay workflow requirements.

Covalent Inhibitor Workflows

Use KRAS G12C proteins for covalent inhibitor profiling, nucleotide-state assays, effector binding studies, and biochemical screening workflows.
