Immunofluorescent analysis of beta-actin (green) in HeLa cells. Cells were fixed and permeabilized with ice-cold methanol for 10 minutes at room temperature, and blocked with 0.3% BSA in PBS for 15 minutes at room temperature. Cells were probed with a beta-actin monoclonal antibody (Product # MA1-140) at a dilution of 1:2000, or incubated in blocking buffer as a negative control, overnight at 4°C, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (Product # 35502) at a dilution of 1:1000 for 30 minutes at room temperature. Nuclei (blue) were stained with DAPI (Product # 62248). Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

By Western blot, MA1-140 detects a prominent ~42kD protein in human, mouse, non-human primate, and rat whole cell lysates.
For visualization of actin filaments by immunofluorescence, fixation and permeabilization with methanol is required.
Beta-actin is one of six different actin isoforms which have been identified. Actins are highly conserved proteins that are involved in cell motility, structure and integrity. Because beta-actin is ubiquitously expressed in all eukaryotic cells, it is frequently used as a loading control for assays involving protein detection, such as Western blotting. Antibodies to beta-actin provide a specific and useful tool in studying the intracellular distribution of beta-actin and the static and dynamic aspects of the cytoskeleton.
