Our Abpromise guarantee covers the use of ab189254 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P 1/1000 - 1/2000. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Detects a band of approximately 50 kDa (predicted molecular weight: 43 kDa).
IP 1/30.


  • Function

    Component of the sarcoglycan complex, a subcomplex of the dystrophin-glycoprotein complex which forms a link between the F-actin cytoskeleton and the extracellular matrix.
  • Tissue specificity

    Most strongly expressed in skeletal muscle. Also expressed in cardiac muscle and, at much lower levels, in lung. In the fetus, most abundant in cardiac muscle and, at lower levels, in lung. Also detected in liver and kidney. Not expressed in brain.
  • Involvement in disease

    Defects in SGCA are the cause of limb-girdle muscular dystrophy type 2D (LGMD2D) [MIM:608099]; also known as Duchenne-like muscular dystrophy autosomal recessive type 2 or severe childhood autosomal recessive muscular dystrophy (SCARMD). LGMD2D is an autosomal recessive degenerative myopathy characterized by progressive muscle wasting from early childhood with loss of independent ambulation by teenage years. Muscle biopsy shows necrosis, decreased immunostaining for alpha sarcoglycan, and adhalin deficiency. The phenotype is less severe than LGMD2C.
  • Sequence similarities

    Belongs to the sarcoglycan alpha/epsilon family.
  • Cellular localization

    Cell membrane > sarcolemma. Cytoplasm > cytoskeleton.

  • Immunhistochemical analysis of paraffin-embedded Human skeletal muscle tissue labeling alpha Sarcoglycan with ab189254 at 1/2000 dilution, followed by prediluted HRP Polymer for Rabbit IgG. Counter stained with Hematoxylin.

  • Immunoprecipitation analysis of human skeletal muscle tissue lysate labeling alpha Sarcoglycan using ab189254 at 1/50 dilution (Lane 1).
