General description

Actin is a highly abundant and conserved protein. It can transition between the monomeric (G-actin) and filamentous (F-actin) forms, which is influenced by external factors. Actin is expressed in smooth, skeletal and cardiac muscles.


Actin from bovine muscle has been used as an internal standard and positive control during western blotting.

Biochem/physiol Actions

Actin is involved in a wide variety of cellular processes like cell migration, phagocytosis, cell polarity and shape. It associates with myosin and aids in muscle contraction. The protein acts as a building block of microfilaments.

Physical form

Lyophilized powder containing Tris, ATP and CaCl2
