| Product Specific InformationMA5-15739 detects beta actin from human, mouse, rat, rabbit, and chicken samples. MA5-15739 has been successfully used in Western blot, IHC (P), FACS and ELISA. MA5-15739 may be stored at 4°C short term. Add 0.05% sodium azide if desired. For long term storage, store at -20°C, avoiding freeze/thaw cycles.Background/Target InformationBeta actin is one of six actin isoforms which have been identified. Beta actin is a non-muscle cytoskeletal protein in all human cell types and is involved in cell motility, structure, and integrity. There are six different actin isoforms in human. The beta isoform of actin, along with gamma actin, coexist in most cell types as components of the cyto-skeleton. Beta actins are cytoplasmic proteins ubuquitously expressed in all eukaryotic cells. Polymerization of globular actin (G-actin) leads to a structural filament (F-actin) in the form of two stranded helix. 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.For Research Use Only.

beta Actin Loading Control Antibody (MA5-15739) in IHC (P)Immunohistochemistry analysis of Beta Actin showing staining in the cytoskeleton of paraffin-embedded mouse skeletal muscle tissue (right) compared with a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a Beta Actin loading control antibody (Product # MA5-15739) diluted in 3% BSA-PBS at a dilution of 1:200 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting. |
