Anti-ARRB2 Antibody

Primary antibodies targeting beta-arrestin 2 enable researchers to investigate GPCR desensitization, receptor internalization, and downstream scaffolding functions across human, mouse, and rat model systems. This unconjugated rabbit polyclonal reagent from Antibodies.com is validated for Western blot and immunofluorescence workflows, making it suited for studies examining arrestin-mediated signal regulation in cell lysates and fixed tissue preparations. Supplied as 100 µl of liquid, the antibody recognizes endogenous ARRB2 and supports detection experiments that probe clathrin-mediated endocytosis, beta-adrenergic receptor trafficking, and arrestin-dependent MAPK or Akt pathway activation.

Polyclonal reactivity broadens epitope coverage compared with monoclonal alternatives, which is helpful when monitoring post-translational modifications or isoform-specific responses. Researchers studying chemokine receptor signaling, opioid receptor desensitization, or dopaminergic pathway modulation frequently rely on anti-ARRB2 reagents to map receptor fate after agonist stimulation. The unconjugated format also allows flexible secondary antibody pairing and custom labeling strategies in advanced imaging or co-immunoprecipitation protocols.
