Anti-Actin Antibody

Actin is one of the most abundant and highly conserved cytoskeletal proteins in eukaryotic cells, where it participates in muscle contraction, cell motility, cytoskeletal organization, and intracellular transport. This unconjugated polyclonal reagent from Antibodies.com is raised in rabbit and recognizes actin across human, mouse, and rat samples, making it a versatile loading-control and structural-protein tool for cross-species studies.

Validated for western blot, immunohistochemistry, and ELISA workflows, the antibody is supplied as a 100 µl liquid aliquot. Its unconjugated format lets researchers conjugate it to HRP, biotin, or a fluorophore of choice, adapting detection chemistry to the experimental system. Polyclonal reactivity broadens epitope coverage within the actin protein, useful when probing isoforms such as α-, β-, and γ-actin that share substantial sequence homology.

For storage, refrigerate the vial upon arrival, aliquot to avoid repeated freeze-thaw cycles, and store frozen at -20 °C for long-term use. Protect from light and handle on ice to preserve antibody activity. Intended for research use only.
