Overview

  • Product nameAnti-Alpha Skeletal Muscle Actin antibody [Alpha Sr-1]
    See all Alpha Skeletal Muscle Actin primary antibodies
  • Description
    Mouse monoclonal [Alpha Sr-1] to Alpha Skeletal Muscle Actin
  • SpecificityIn Western blotting of pure rabbit striated muscle actin or of total extracts from different tissues, e.g. rat striated muscle, rat myocardium, rat aortic media, human fibroblasts and pure chicken gizzard actin, ab28052 labels alpha-skeletal (alpha-sarcomeric) and alpha-cardiac muscle actins. No labelling is observed with actin from fibroblasts (alpha-smooth muscle and beta-cytoplasmic actin), aorta (alpha-smooth muscle actin), or chicken gizzard (gamma-smooth muscle actin).

Target

  • FunctionActins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.
  • Involvement in diseaseDefects in ACTA1 are the cause of nemaline myopathy type 3 (NEM3) [MIM:161800]. A form of nemaline myopathy. Nemaline myopathies are muscular disorders characterized by muscle weakness of varying severity and onset, and abnormal thread-or rod-like structures in muscle fibers on histologic examination. The phenotype at histological level is variable. Some patients present areas devoid of oxidative activity containg (cores) within myofibers. Core lesions are unstructured and poorly circumscribed.
    Defects in ACTA1 are a cause of myopathy congenital with excess of thin myofilaments (MPCETM) [MIM:161800]. A congenital muscular disorder characterized at histological level by areas of sarcoplasm devoid of normal myofibrils and mitochondria, and replaced with dense masses of thin filaments. Central cores, rods, ragged red fibers, and necrosis are absent.
    Defects in ACTA1 are a cause of congenital myopathy with fiber-type disproportion (CFTD) [MIM:255310]; also known as congenital fiber-type disproportion myopathy (CFTDM). CFTD is a genetically heterogeneous disorder in which there is relative hypotrophy of type 1 muscle fibers compared to type 2 fibers on skeletal muscle biopsy. However, these findings are not specific and can be found in many different myopathic and neuropathic conditions.

  • ab28052 staining Alpha Skeletal Muscle Actin in rabbit heart tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 10% formalin and blocked with 10% serum for 30 minutes at 25°C; antigen retrieval was by heat mediation. Samples were incubated with primary antibody (1/100 in 10% goat serum) for 24 hours at 4°C. An undiluted Alexa Fluor® 488-conjugated goat anti-mouse IgG polyclonal (1/250) was used as the secondary antibody.

  • ab28052 at dilution 1/200 staining alpha sarcomeric actin from rat neonatal cardiac myocytes by immunocytochemistry. The cells were fixed in paraformaldehyde, permeabilized in 0.1% NP40 and incubated with the antibody for 45 minutes. A Cy3® donkey anti-mouse antibody was used as the secondary antibody.
