Immunogen Synthetic NH2 terminus decapeptide of cardiac isoform of Actin.
Clone AC1-20-4-2
Isotype IgG1
Specificity 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.
Background 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.
Gene ID 70
NCBI Accession NP_005150
UniProt P68032
Application Notes 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.
Restrictions For Research Use only
Reconstitution Restore in 1.0 mL distilled water.
Buffer Final Solution contains PBS, pH 7.4 with 0.09 % Sodium Azide as preservative and 0.5 % BSA as stabilizer.
Preservative Sodium azide
Precaution of Use This product contains sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.
Handling Advice Dilute only prior to immediate use. Avoid cycles of freezing and thawing.
Storage 4 °C/-20 °C
Storage Comment Store the antibody (undiluted) at 2-8 °C for one month or (in aliquots) at -20 °C for longer.
