Application

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.

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.

Physical form

Lyophilized powder containing Tris, ATP and CaCl₂
