The ADP-ribosylation factor 1 (ARF1) antibody is a key tool for studying the function and localization of ARF1. a small GTP-binding protein belonging to the ARF family. ARF1 plays a central role in intracellular vesicular trafficking, primarily regulating the formation of COPI-coated vesicles involved in retrograde transport between the Golgi apparatus and endoplasmic reticulum. It also participates in lipid metabolism, organelle structure maintenance, and actin cytoskeleton dynamics. ARF1 antibodies are typically generated using recombinant ARF1 protein or synthetic peptides corresponding to conserved regions, with common host species including rabbits and mice. These antibodies enable the detection of ARF1 (~20 kDa) in techniques such as Western blotting, immunofluorescence, and immunohistochemistry. Researchers utilize ARF1 antibodies to investigate its involvement in cellular processes like secretion, autophagy, and receptor signaling, as well as its dysregulation in diseases such as cancer, neurodegenerative disorders, and metabolic syndromes. Specificity is often validated using ARF1-knockout cell lines or siRNA-mediated knockdown. As ARF1 activation is tightly regulated by GTP/GDP cycling, some studies employ conformation-specific antibodies to distinguish its active GTP-bound state. Commercial ARF1 antibodies are widely available, with validation data typically including reactivity across human, mouse, and rat samples.
