Anti-RAC1 (phospho S71) Antibody

This phospho-specific polyclonal reagent from Antibodies.com targets RAC1 at serine 71, a regulatory site on the small GTPase involved in cytoskeletal remodeling, lamellipodia formation, and cell migration signaling. Raised in rabbits and purified as an IgG antibody, it is supplied as 200 µl of unconjugated product suitable for western blot detection across human, mouse, and rat samples.

The S71 phospho-epitope is associated with Akt-mediated regulation of RAC1 activity, making this reagent useful for studies of growth-factor signaling, motility, and invasion pathways. Recommended storage at -20 °C in single-use aliquots helps preserve phospho-specific binding activity through repeated freeze-thaw cycles, and the unconjugated format allows flexible reporter selection for downstream chemiluminescent or fluorescent WB workflows. Each lot is validated for use in WB applications to distinguish the phosphorylated form of RAC1 from total RAC1 protein in lysates derived from the listed reactive species.
