Specificity |  | Signet’s anti-human spectrin (Clone D8B7) is developed against the alpha II spectrin SH3 domain (Xu et al., 2001). 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). 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. |
Uses |  | This antibody is effective in immunoblotting, immunofluorescence (IF), immunohistochemistry (IHC) and ELISA. |
Suggested Working Dilution |  | The optimal working dilution should be determined for each specific assay condition. - Western blot: 1:100 - 1:1,000
- IF: 1:100 - 1:500
- IHC: 1:10 - 1:50 (Frozen only)
- ELISA: 1:100,000- 1:1,000,000
