Anti-RAC1 Antibody

Raised in rabbit and affinity-purified as a polyclonal IgG, this unconjugated antibody recognizes RAC1, a 21 kDa Rho-family GTPase that regulates actin cytoskeleton dynamics, lamellipodia formation, and cell migration. Antibodies.com delivers it as a 200 µl vial validated for western blot and immunofluorescence workflows on human, mouse, and rat-derived samples. It is useful for dissecting receptor tyrosine kinase signaling, membrane ruffling, and the small GTPase cycle between active GTP-bound and inactive GDP-bound states. The unconjugated format offers flexible pairing with the researcher's preferred secondary reagent, including HRP-, fluorophore-, or biotin-conjugated anti-rabbit IgG for downstream detection. Recommended for research on cytoskeletal remodeling, focal adhesion turnover, and RAC1-driven invasion pathways in oncology and neurobiology models.
