This antibody is specific for Fetal (Cardiac) isoform of Actin. Clone Ac1 represents an excellent marker for cardiac tissue. It discriminates fetal (cardiac) alpha-Actin from all other Actin isoforms. Mab Ac1-20.4.2 shows no cross reaction with other Actin isoforms present in skeletal and smooth muscle, provided that stringent conditions have been applied (see Special Treatment).
Cross-Reactivity (Details)
Species reactivity (tested):Human, Bovine, Rabbit and Chicken.
Purification
Affinity Chromatographyon Protein G.
Immunogen
Synthetic NH2 terminus decapeptide of cardiac isoform of Actin.
ELISA: 1/500. Western Blot: 1/1000 (using the ECL-enhanced procedure). Immunohistochemistry on Frozen Sections. Immunohistochemistry on Paraffin-Embedded Tissue: 1/10 (After microwave treatment). Incubation time: 1 h at RT. Special Treatment: It is necessary to include 0.5 M NaCl in all washing buffers forapplication on Frozen tissue and 1 M NaCl for Western blotting and ELISA to enhancespecifity. This is not necessary for Paraffin sections. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Actins are highly conserved proteins that are involved in cell motility, structure, and integrity. ACTB/ACTC are nonmuscle cytoskeletal actins and major constituents of the contractile apparatus. Defects in ACTB are a cause of juvenile-onset dystonia. Defects in ACTC have been associated with idiopathic dilated cardiomyopathy (IDC) and familial hypertrophic cardiomyopathy (FHC). Fetal Actin can be localized in regenerating skeletal muscle after injury (in satellite cells) and in veins of the umbelical cord.
