Anti-ARPC1A Antibody

Produced in rabbit as a polyclonal reagent, this unconjugated primary antibody targets ARPC1A, the p41 subunit of the seven-protein Arp2/3 actin nucleation complex. The Antibodies.com affinity-purified reagent recognizes the p41 band in Western blot applications and labels cellular structures in immunohistochemistry on human, mouse, and rat tissue sections.

ARPC1A scaffolds branched actin filament networks that drive lamellipodial protrusion, membrane remodeling, vesicular trafficking, and immune synapse assembly in motile cells. Each vial contains 100 µL of antiserum supplied in a buffer compatible with standard immunolabeling protocols, including multiplex fluorescence detection when paired with species-matched secondary antibodies.

For best stability, store at -20 °C in working aliquots to limit freeze-thaw cycles; refrigerated short-term handling at 4 °C is acceptable during active experiments.
