Anti-alpha Tubulin Antibody

α-Tubulin is a ~50 kDa globular protein that heterodimerizes with β-tubulin to form the building blocks of microtubules, the dynamic cytoskeletal filaments that drive mitosis, intracellular trafficking, and maintenance of cell morphology. Antibodies against this conserved cytoskeletal component are commonly used as reference reagents in cell biology, serving as reliable loading controls in Western blot because expression levels remain stable across many experimental conditions, while immunofluorescence and immunohistochemistry enable direct visualization of microtubule networks in fixed cells and tissue sections. Provided as 100 µg of unconjugated liquid antibody, this mouse IgG1 monoclonal from Antibodies.com is intended for WB, IP, IF, and IHC workflows, cross-reacts with a broad panel of species, and reflects the strong evolutionary conservation of the target. For long-term stability, aliquot the reagent and store at -20 °C, protecting the vial from light and limiting freeze-thaw cycles.
