The spectrins are a family of widely distributed cytoskeletal proteins which are involved in actin crosslinking. Spectrin α-chain heterodimerizes with tissue-specific β-chains. It is specifically expressed in nonerythrocytic cells. The protein has been implicated in other cellular functions including DNA repair and cell cycle regulation. Mutations in the gene are the cause of early infantile epileptic encephalopathy. Fodrin, a spectrin that seems to be involved in secretion, interacts with calmodulin in a calcium-dependent manner and is thus a candidate for the calcium-dependent movement of the cytoskeleton at the membrane.Product Details

- Recommended Usage
Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 5.0 µg/ml is suggested. For immunocytochemistry, a concentration of 1.0 μg/ml is recommended. For Western blotting, the suggested use of this reagent is 0.05 - 2.0 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Clone D8B7 is a specific marker for human, rat and mouse alpha II spectrin or fodrin. In cerebellar cell cultures, it labels axons and periphery of cell bodies consistent with localization of fodrin (reviewed in Bennett, 1993; Goodman, 1995 & De Matteis, 2000)4, 6, 8. It does not cross-react with alpha I (erythroid) spectrin SH3 domain.
This antibody was developed against a recombinant alpha II spectrin (non-erythroid spectrin or fodrin) SH3 domain. It was subsequently purified via ammonium sulfate precipitation.
Reactivity to Drosophila was only verified with the purified format.
- Additional Product Notes
For Western blotting, the suggested use of this reagent is 0.05 - 1 µg/ml in human, mouse, and rat and 0.1 - 2 µg/ml in Drosophila.
