Immunofluorescent analysis of beta-actin (red) in HeLa cells. Cells were fixed and permeabilized with ice-cold methanol for 10 minutes at room temperature, blocked with 0.3% BSA in PBS for 15 minutes, and probed with a DyLight 650-conjugated beta-actin monoclonal antibody (Product # MA5-15739-D650) at a dilution of 1:50 overnight at 4°C. Nuclei (blue) were stained with DAPI (Product # 62247). Images were taken on Thermo Scientific ToxInsight Instrument at 20X magnification.

MA5-15739-D650 has been successfully used in immunofluorescence. DyLight 650 has an excitation/emission of 652/672 nm. 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.
