  • Description
    Mouse monoclonal [DB2] to beta 1 Spectrin
  • Specificity
    ab86184 is specific to the erythroid beta 1 Spectrin.
  • Tested applications
    Suitable for: WB, IP, ICC/IFmore details
  • Species reactivity
    Reacts with: Human

    Ghost proteins of human red blood cells.

  • General notes

    ab86185 is derived from the hybridoma produced by fusion between myeloma cells and Balb/c spleen cells.
    Because the beta 1 Spectrin protein is also present in the membranes of human skeletal muscle cells, ab86185 can also be used to monitor the integrity of muscle cell plasma membranes.



Our Abpromise guarantee covers the use of ab86185 in the following tested applications.

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

WB 1/1000. Predicted molecular weight: 246 kDa.
IP Use at an assay dependent dilution.
ICC/IF Use at an assay dependent dilution.


  • Function
    Spectrin is the major constituent of the cytoskeletal network underlying the erythrocyte plasma membrane. It associates with band 4.1 and actin to form the cytoskeletal superstructure of the erythrocyte plasma membrane.
  • Involvement in disease
    Defects in SPTB are the cause of elliptocytosis type 3 (EL3) [MIM:182870]. EL3 is a Rhesus-unlinked form of hereditary elliptocytosis, a genetically heterogeneous, autosomal dominant hematologic disorder. It is characterized by variable hemolytic anemia and elliptical or oval red cell shape.
    Defects in SPTB are the cause of spherocytosis type 2 (SPH2) [MIM:182870]; also known as hereditary spherocytosis type 2 (HS2). Spherocytosis is a hematologic disorder leading to chronic hemolytic anemia and characterized by numerous abnormally shaped erythrocytes which are generally spheroidal. SPH2 is characterized by severe hemolytic anemia. Inheritance is autosomal dominant.
  • Sequence similarities
    Belongs to the spectrin family.
    Contains 2 CH (calponin-homology) domains.
    Contains 17 spectrin repeats.
  • Post-translational
    The first phosphorylation event occurs on Ser-2114, followed by Ser-2125, Ser-2123, Ser-2128, Ser-2117, and Thr-2110.
  • Cellular localization
    Cytoplasm > cytoskeleton. Cytoplasm > cell cortex.
