D8B7_Biotin_Alpha-II-Spectrin_Antibody_1_070819
Western blot of Biotin anti-Alpha-II-Spectrin antibody (clone D8B7). Lane 1: Molecular weight marker; Lane 2: 20 µg of human brain membrane lysate; Lane 3: 20 µg of mouse brain membrane lysate; Lane 4: 20 µg of rat brain membrane lysate. The blot was incubated with 1 µg/mL of the primary antibody overnight at 4°C, followed by incubation with HRP-labeled streptavidin (Cat. No. 405210). Enhanced chemiluminescence was used as the detection system. The lower band in lane 2 is spectrin breakdown product (SBDP).

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.

IHC-P - Validated

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.5 - 5.0 µg per ml. For immunohistochemistry, a concentration range of 5.0 - 10 µg/ml is suggested. 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 validated with the purified format.
