Description

General description

In staining of chicken gizzard ultrathin tissue cryosections, the antibody labels the dense bodies and longitudinal channels linking consecutive dense bodies that are also occupied by desmin and the membrane-associated dense plaque. It does not stain adult cardiac and skeletal muscles except for traces due to contaminations of the sample with non-muscle cells, or if embryonic tissue is being used.

Monoclonal Anti-β-Actin (mouse IgG1 isotype) is derived from the AC-15 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Actin is one of the most conserved eukaryotic proteins, it is expressed in mammals and birds as at least six isoforms. Four of them represent the differentiation markers of muscle tissues and two are found practically in all cells. There are three α-actins (α-skeletal, α-cardiac, and α-smooth muscle), one β-actin (β-nonmuscle), and two γ-actins (γ-smooth muscle and γ-non-muscle). Actin isoforms show >90% overall sequence homology, but only 50−60% homology in their 18 NH2-terminal residues. The NH2-terminal region of actin appears to be a major antigenic region and may be involved in the interaction of actin with other proteins such as myosin. The antibody can be used for staining of acetone-fixed frozen sections, EM preparations, and microinjection experiments. B5, ethanol, methacam, or Bouin′s solutions can be used as fixatives. The epitope recognized by the antibody is resistant to formalin-fixed and paraffin-embedding.

Specificity

Monoclonal Anti β-Actin antibody recognizes an epitope located on the N-terminal end of the β-isoform of actin. The antibody specifically labels β-actin in a wide variety of tissues and species using immunoblotting (42 kDa), immunofluorescent staining of cultured cell lines, and immunohistochemistry.

Immunogen

slightly modified β-cytoplasmic actin N-terminal peptide, Ac-Asp-Asp-Asp-Ile-Ala-Ala-Leu-Val-Ile-Asp-Asn-Gly-Ser-Gly-Lys, conjugated to KLH.

Application

Monoclonal Anti-β-Actin antibody produced in mouse has also been used:

• in immunofluorescence staining
• in immunoblotting
• in immunohistochemistry
• as a control for protein arrays

Monoclonal mouse anti-actin antibody was used as a loading control for western blot analysis of immunoprecipitated proteins from rat dorsal root ganglion cocultures.

Monoclonal mouse anti-actin was used as a loading control for western blot analysis of rat liver protein lysates.

Biochem/physiol Actions

Actin and myosin are constituents of many cell types and are involved in a myriad of cellular processes including locomotion, cytokinesis, cytoplasmic streaming, secretion and phagocytosis. The actin in cells of various species and tissue origin is very similar in its immunological and physical properties.

Physical form

Supplied as ascites fluid with 15mM sodium azide as a preservative.
