rabbit skeletal α-actinin

General description

α-Actinin is a 100kDa actin-binding protein that is found in muscle as well as non-muscle cells. In smooth muscles, α-actinin is present in dense bodies and plaques whereas in normal skeletal muscles, it is associated with z-discs that define muscle sarcomeres.
Mouse monoclonal anti-α-actinin (sarcomeric) antibody stains thymic myoid cells. The antibody exhibits wide reactivity with human and animal muscle tissue.

The antibody is specific for α-skeletal and α-cardiac muscle actinins. The antibody labels Z lines and dots in stress fibers of skeletal muscle in myotubes but does not react with non-skeletal muscle elements (e.g., connective tissue, epithelium, nerves, smooth muscle).


Cardiac myocytes were stained with monoclonal mouse anti-actinin to visualize the Z-lines after fixation in pre-cooled methanol/acetone mix (1:1) for 10 minutes at 4 °C.

Mouse monoclonal anti-α-actinin (sarcomeric) antibody is suitable for immunohistochemistry (1:800), ELISA, immunofluorescence and western blot (1:2,500) applications.
