| Specificity |  | Signet’s anti- human spectrin binding protein (clone 4E2) was developed against the spectrin SH3 domain binding protein Hssh3bp1 (Ziemnicka-Kotula et al., 1998). Hssh3bp1 is a marker of macropinocytic vesicles and a potential regulator of macropinocytosis (Xu et al., 2000). This antibody was developed against recombinant Hssh3bp1 (human spectrin SH3 domain binding protein 1). |
| Uses |  | This antibody is effective in immunoblotting, immunofluorescence (IF) and immunohistochemistry (IHC). |
| Suggested Working Dilution |  | The optimal working dilution should be determined for each specific assay condition. - Western: 1:1,000-1:2,000
- IF: 1:100-1:500
- IHC: 1:40-1:100
Tissue Sections: Formalin fixed, paraffin embedded sections and frozen sections Pretreatment: For optimal staining, the sections should be pretreated with an antigen unmasking solution such as Retrieve-All 1 (SIG-31910). Incubation: Overnight at 4°C. |
| Notes |  | Spectrin Binding Protein Monoclonal Antibody (SIGNET)Positive tissue (human): Prostate |
| Storage |  | Store at -20°C or below. Upon initial thawing, apportion into working aliquots and store at -20°C or below. Avoid repeated freeze-thaw cycles to prevent denaturing the antibody. Do not store in frost-free freezers. |
