Anti-β-Actin (D8) Antibody

Raised in rabbit and supplied by Antibodies.com, this polyclonal antiserum targets the D8 epitope region of beta-actin, a highly conserved 42 kDa cytoskeletal protein widely used as an internal loading control for Western blot normalization. The antibody is provided at 1 mg/ml in phosphate buffered saline (PBS) with 0.05% sodium azide at approximately pH 7.2, packaged as 100 ul of ready-to-use reagent. Validated specifically for Western blot on human, mouse, and rat samples, the unconjugated format allows flexible pairing with custom reporter-conjugated secondary antibodies. Polyclonal reactivity improves tolerance for minor sequence variation between species and provides robust signal across denatured lysate preparations commonly prepared for SDS-PAGE workflows.
