Our Abpromise guarantee covers the use of ab72239 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
WB 1/2000 - 1/10000. Detects a band of approximately 274 kDa (predicted molecular weight: 274 kDa).
IP Use at 2-5 µg/mg of lysate.
ICC/IF Use a concentration of 1 µg/ml.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

Target

  • FunctionFodrin, which seems to be involved in secretion, interacts with calmodulin in a calcium-dependent manner and is thus candidate for the calcium-dependent movement of the cytoskeleton at the membrane.
  • Tissue specificityIsoform 2 is present in brain, lung and kidney (at protein level).
  • Sequence similaritiesBelongs to the spectrin family.
    Contains 2 CH (calponin-homology) domains.
    Contains 1 PH domain.
    Contains 17 spectrin repeats.
  • Post-translational
    modifications
    Isoform 2 is phosphorylated on Ser-8 and Ser-10.
  • Cellular localizationCell membrane and Cytoplasm > cytoskeleton. Cytoplasm > myofibril > sarcomere > M line. Colocalizes with ANK2 in a distinct intracellular compartment of neonatal cardiomyocytes.

  • IHC image of ab72239 staining in human normal tonsil formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab72239, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • ICC/IF image of ab72239 stained A431 cells. The cells were 100% methanol fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab72239, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
