D8B7_Ascites_AlphaIISpectrin_Antibody_1_081318
Western blot of anti-Alpha-II Spectrin antibody (clone D8B7). Lane 1: Molecular weight marker; Lane 2: 20 µg of human brain lysate; Lane 3: 20 µg of mouse brain lysate; Lane 4: 20 µg of rat brain lysate; Lane 5: 20 µg of 3T3 cell lysate; Lane 6: 20 µg of HeLa cell lysate. The blot was incubated with the primary antibody at 1:2000 dilution overnight at 4°C, followed by incubation with HRP labeled goat anti-mouse IgG (Cat. No. 405306). Enhanced chemiluminescence was used as the detection system.

    ICC staining of anti-Alpha-II Spectrin antibody (clone D8B7) on HeLa cells. The cells were fixed with 4% PFA, permeabilized with a buffer containing 0.1% Triton X-100 and 0.25% BSA, and blocked with 2% normal goat serum and 0.02% BSA. The cells were then incubated with the primary antibody at 1:1000 dilution overnight at 4°C, followed by incubation with 2.5 µg/ml of Alexa Fluor® 594 goat anti-Mouse IgG for one hour at room temperature. Nuclei were counterstained with DAPI, and the slides were mounted with ProLongTM Gold Antifade Mountant. The image was captured with a 40X objective. Scale bar: 50 µm

Description

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.

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 1:2000 - 1:4000 dilution. For immunohistochemistry on formalin-fixed paraffin-embedded tissue, a dilution of 1:1000 is suggested. For immunocytochemistry, a dilution of 1:1000 is recommended. 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.
