Technical Data
Actin, beta
Beta-actin is one of six different actin isoforms which have been identified. Actins are highly conserved proteins that are involved in cell motility, structure, and integrity. Because beta-actin is ubiquitously expressed in all eukaryotic cells, it is frequently used as a loading control for assays involving protein detection, such as Western Blot. Antibodies to beta-actin provide a specific and useful tool in studying the intracellular distribution of beta-actin and the static and dynamic aspects of the cytoskeleton.

Suitable for use in ELISA, Western Blot, Immunohistochemistry and Immunofluorescence. Other applications have not been tested.

Recommended Dilutions:
Western Blot: 0.5-1ug/ml. Useful as a loading control for a wide variety of cell extracts including human foreskin fibroblasts or chicken fibroblasts.
Immunohistochemistry (Paraffin and frozen): The epitope recognized by the antibody is resistant to paraffin or formalin-fixed tissue sections. Acetone fixation or B5, Methacarn, ethanol or Bouins solution may also be used as fixatives.
Immunofluorescence (IC): 10-40ug/ml on methanol/acetone fixed samples. Staining of chicken gizzard ultra-thin sections labels the dense bodies, longitudinal channels and membranes associated dense-plaque.
Optimal dilutions to be determined by the researcher.

Positive Control:
Cultured human or chicken fibroblasts
