Anti-ARL4A Antibody

ARL4A (ADP-ribosylation factor-like protein 4A) is a small GTP-binding protein of the Arl/Arf family that participates in membrane trafficking, cytoskeletal remodeling, and cell migration. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against the human ARL4A sequence and is validated for Western blot and immunohistochemistry on human samples. The polyclonal format allows recognition of multiple epitopes across the target, which is helpful when probing denatured protein in lysates and when mapping ARL4A distribution in fixed tissue sections.

ARL4A expression has been studied in lung, colorectal, and head-and-neck cancers, where altered levels have been linked to proliferation and invasive behavior, making it a relevant marker for basic research into small GTPase signaling and tumor cell biology. The antibody is supplied as a 100 µL liquid aliquot and is reactive with human tissue; researchers commonly pair this reagent with appropriate secondary antibodies for chromogenic or fluorescent detection depending on the application. Store refrigerated and avoid repeated freeze-thaw cycles to preserve activity.
