Anti-Tubulin α Antibody

This rabbit polyclonal reagent from Antibodies.com targets the alpha subunit of tubulin, a ~50 kDa cytoskeletal protein that forms microtubule heterodimers with beta-tubulin. Provided as an unconjugated preparation in a 100 µl volume, it supports western blot detection of tubulin alpha across human, mouse, and rat samples and is also validated for ELISA workflows. The polyclonal format increases the likelihood of recognizing multiple epitopes along the target, which is useful when probing conserved cytoskeletal components or when working across the three species listed in the reactivity profile. Researchers routinely apply tubulin alpha antibodies as loading controls on western blot membranes so band intensity can be normalized between lanes using whole-cell lysates. Because the reagent is unconjugated, it can be paired with a lab's own choice of HRP, fluorescent, or biotinylated secondary detection reagents. Aliquoting upon arrival and storage at 4 °C in the supplied vial preserves activity for repeated short-term use across blotting and immunoassay experiments.
