RAS-Family GTPases

Selecting a RAS-Family GTPase for Your Assay

RAS-family and related small GTPase assays often depend on isoform, mutation, nucleotide state, tag placement, immobilization strategy, and downstream binding partner. Use KRAS, NRAS, HRAS, RALA, RALB, RHEB, and related recombinant proteins to support pathway biology, effector-binding studies, nucleotide-state workflows, and drug discovery research.

RAS Isoforms and Mutants

Select KRAS, NRAS, HRAS, and mutant RAS-family proteins by isoform, mutation, nucleotide-state requirements, tag placement, and assay workflow.

Related Small GTPases

Use RALA, RALB, RHEB, and related small GTPase proteins for signaling studies, effector interactions, pathway assays, and druggability research.

Custom Small GTPases

Request custom mutations, nucleotide loading, tag placement, linker(s), biotinylation, formulation, or bulk production for RAS-family and related small GTPase proteins.

Build a RAS-Family GTPase Assay Workflow

Pair RAS-family and related small GTPase proteins with defined nucleotide-loading formats, biotinylated capture reagents, pathway interaction partners, or custom recombinant protein services.
