Our Abpromise guarantee covers the use of ab9465 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-P||1/25 - 1/50. ABC method. We suggest an incubation period of 60 minutes at room temperature. However, depending upon the fixation conditions and the staining system employed, optimal incubation and dilutions should be determined by the user.|
|IHC-Fr||Use at an assay dependent concentration.|
|ICC/IF||Use at an assay dependent concentration. PubMed: 17383364|
|IHC-FoFr||Use at an assay dependent concentration. PubMed: 20019242|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 103 kDa (predicted molecular weight: 103 kDa).|
FunctionF-actin cross-linking protein which is thought to anchor actin to a variety of intracellular structures. This is a bundling protein.
Tissue specificityExpressed in both skeletal and cardiac muscle.
Involvement in diseaseDefects in ACTN2 are the cause of cardiomyopathy dilated type 1AA (CMD1AA) [MIM:612158]. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.
Sequence similaritiesBelongs to the alpha-actinin family.
Contains 1 actin-binding domain.
Contains 2 CH (calponin-homology) domains.
Contains 2 EF-hand domains.
Contains 4 spectrin repeats.
Cellular localizationCytoplasm > myofibril > sarcomere > Z line. Colocalizes with MYOZ1 and FLNC at the Z-lines of skeletal muscle.

ab9465 staining Sarcomeric Alpha Actinin in mouse heart tissue by Immunohistochemistry (Frozen sections). Serial longitudinal (12 µm) sections from wt hearts were incubated with ab9465. Nuclei were visualized with DAPI.
Immunocytochemistry/Immunofluorescence analysis of H9 hESC and CBiPSC6.2 cells labelling Sarcomeric Alpha Actinin (green) with ab9465 at a dilution of 1/200. An Alexa Fluor® 488-conjugated goat anti-mouse IgG was used as the secondary antibody (1/200).
Immunofluorescence staining of SNAIL1 and cardiac cell type markers (alpha actinin-cardiomyocyte marker; 1/100 dilution) in the ventricular infarct zone of LAD surgery mice. Scale bars: 50 microns.
5 um sections of paraffin or OCT embedded hearts were utilized for Massons Trichrome Staining and immunofluorescence. For SNAIL1 immunofluorescence, antigen retrieval was done in Nuclear Decloaker solution and TSA plus kit was used to amplify SNAIL1 signal.
