Beta Actin Antibodies

Beta actin antibodies provide a specific and useful tool for studying the intracellular distribution of beta actin and the static and dynamic aspects of the cytoskeleton. Because it is ubiquitously expressed in all eukaryotic cells, beta actin is frequently used as a loading control.

Beta actin is one of six isoforms of actin that have been identified in mammals. Actin is the primary component of the cytoskeleton, and beta actin is predominantly expressed in non-muscle cells, where it controls cell structure and motility.

Quality Invitrogen beta actin antibodies are available for a variety of research needs. We also offer fluorescent and enzyme-conjugated versions for your added convenience.

Featured product data

Beta Actin Antibody MA5-15739 immunohistochemistry data

Immunohistochemical analysis of beta actin showing staining in the cytoskeleton of paraffin-embedded human breast carcinoma (right), compared with a negative control without primary antibody (left). The staining of the beta actin with the loading control antibody (Cat. No. MA5-15739-BTIN) confirms that proteins in the sample are accessible for binding by other primary antibodies.

Beta Actin Antibody MA5-15739-HRP western blot data


Western blot analysis of beta actin was performed by loading 30 μg of various cell lysates in wells of a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and probed with an HRP-conjugated beta actin monoclonal antibody (Cat. No. MA5-15739-HRP). Chemiluminescent detection was performed using SuperSignal West Pico Substrate (Cat. No. 34080).

Beta Actin Antibody MA5-15739 FACS flow cytometry data

Flow cytometry analysis of beta actin in A431 cells (green) compared to an isotype control (blue). Cells were harvested and washed with PBS. Cells were blocked with a 2% solution of BSA-PBS for 30 minutes at room temperature and incubated with a beta actin loading control antibody (Cat. No. MA5-15739-BTIN). Cells were then incubated for 40 min at room temperature in the dark with a secondary antibody conjugated to DyLight 488 dye, and resuspended in PBS for FACS analysis.

Beta Actin MA1-140-A488 fluorescent western blot data


Western blot analysis of beta actin was performed by loading various cell lysates onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a low-fluorescence PVDF membrane and probed with a beta actin monoclonal antibody conjugated to Alexa Fluor 488 dye (Cat. No. MA1-140-A488).
