Figure 2. Immunohistochemistry of TDP-43 lesions. Neuronal cytoplasmic inclusions in dentate gyri of frontotemporal lobar degeneration (FTLD-U) are specifically stained. Bars 100 um. mAb pS409/410 stains ubiquitin-positive inclusions in FTLD-U and ALS without nuclear staining. It does not stain ghost tangles and granulovacuolar degeneration in AD or other related diseases by immunohistochemistry.

Anti TAR DNA-Binding Protein 43 (TDP-43), phospho-Ser409/410 mAb (Clone 11-9) (in PBS)

Application: ELISA, IHC(f), WB 
Clonality: Monoclonal 
Host: Mouse 
Purification: Purified - Affinity 
Reactivity: Human 

Anti-TAR DNA-Binding Protein 43 (TDP-43), phospho-Ser409/410 mAb 11-9 was cloned from mice immunized with diphospho-peptide [CMDSKS(p)S(p)GWGM]. 11-9 recognizes human TDP-43 phosphorylated on serines 409 and 410. 11-9 is validated for western blot, ELISA and IHC(f). This antibody is a powerful tool for biochemical and immunohistochemical analyses of TDP-43 proteinopathy.

TDP-43, a heterogeneous nuclear ribonucleoprotein, was identified as a component of ubiquitin-positive and tau-negative inclusions observed in cases of frontotemporal lobar degeneration (FTLD-U) and amyotrophic lateral sclerosis (ALS). Immunochemical analyses using antibodies generated against phospho- and non-phosphopeptides of human TDP-43 revealed that abnormally phosphorylated full-length TDP-43 (45 kDa), C-terminal fragments (~25 kDa) and smearing substances are deposited as intracellular inclusions in affected regions of FTLD-U and ALS cases.

This antibody is a powerful tool for biochemical and immunohistochemical analyses of neurodegenerative diseases and for evaluation of cellular or animal models of TDP-43 proteinopathy.
