The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesIHC-P: 1/100 - 1/500. Epitope exposure is recommended. Epitope exposure with citrate buffer will enhance staining.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
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 modificationsIsoform 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.
