beta-Actin: Proteins and Enzymes

beta-Actin is a relatively stable non-muscle cytoskeletal protein and has a function in cell structure, cell motility, and cell morphology. Non-muscle beta-Actin is also sometimes referred to as cytoplasmic actin. It is generally thought to be present at a constant level in cells and for this reason, measurement of beta-Actin is generally used as an internal control. Antibodies specific for beta-Actin have been used in Western blot as a loading control for whole cell and cytoplasmic samples. ...
