Anti-beta-Actin, clone 6L12 ZooMAb, Cat. No. ZRB1312, is a recombinant rabbit monoclonal antibody that specifically detects beta-Actin and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected -Actin in C2C12, C6, and COS-1 cell lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected -Actin in human uterus and human stomach tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected -Actin in C2C12 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Target description

Actin, cytoplasmic 1 (UniProt: P60709; also known as beta-Actin) is encoded by the ACTB gene (Gene ID: 60) in human. Actins are ubiquitous eukaryotic proteins that serve as multi-functional, basic building blocks of cytoskeletal microfilaments. They play critical roles in a wide range of cellular processes, including cell division, cell migration, chromatin remodeling, transcriptional regulation, and vesicle trafficking. These functions are attributed to their ability to form filaments, which can quickly assemble and disassemble depending upon the needs of the cell. At least six different actin types have been reported in mammals. Although actins show about 90% overall sequence homology, isoforms do show spatial, temporal, and tissue-specific expression patterns and only 50-60% homology is found in their 18 N-terminal residues. Beta- and gamma-actins are the major structural components of the actin cytoskeleton in non-muscle cells. Beta-actin plays a predominant role in cell migration and its enrichment has also been observed at the leading edge of migrating cells, whereas gamma-actin appears to be more uniformly distributed throughout the cell. In addition, beta-actin can also undergo N-terminal arginylation that regulates lamella formation in motile cells. Beta-actin has also been consistently utilized as a loading control in Western blotting applications due to the fact that its expression is fairly consistent, although its levels can somewhat differ in different tissues and its expression can be affected by certain pathological conditions. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
