Smooth muscle actin has been purified (mol wt ~43 kDa, >95%) from chicken gizzard. Purified preparation is predominantly gamma isoform (80%) and 20% cytoplasmic actin. It is supplied in stabilizing buffer (5.0 mM Tris-HCI pH 8.0, 0.2 mM CaCl2, 0.2 mM ATP and 0.5 mM DTT) as liquid at 1 mg/ml or lyophilized in the buffer. The protein is biologically active using actin polymerization assay.

Actin and myosin are the two major cytoskeleton proteins implicated in cellular movement, secretion, phagocytosis, and kinesis. Actin is one of the most conserved cellular protein. At least 6 actin isoforms have been identified by protein sequence analy
