Background Information

Transactivation response (TAR) DNA-binding protein of 43 kDa (also known as TARDBP or TDP-43) was first isolated as a transcriptional inactivator binding to the TAR DNA element of the HIV-1 virus. Neumann et al. (2006) found that a hyperphosphorylated, ubiquitinated, and cleaved form of TARDBP, known as pathologic TDP-43, is the major component of the tau-negative and ubiquitin-positive inclusions that characterize amyotrophic lateral sclerosis (ALS) and the most common pathological subtype of frontotemporal lobar degeneration (FTLD-U). Various forms of TDP-43 exist, including 18-35 kDa of cleaved C-terminal fragments, 45-50 kDa phospho-protein, 55 kDa glycosylated form, 75 kDa hyperphosphorylated form, and 90-300 kDa cross-linked form. (PMID: 17023659,19823856, 21666678, 22193176). 80007-1-RR is a recombinant rabbit monoclonal antibody recognizing TDP-43 only when phosphorylated at 409/410. Immunohistochemical analyses using this antibody only stain the insoluble inclusions in pathologic tissues without normal diffuse nuclear staining.

Excellent phospho-specific TDP-43 antibody. Tested by IHC in ethanol and NBF fixed FTLD-TDP brains and ALS spinal cord. The antibody works well with citrate buffer and FA as antigen retrieval. The dilutions that worked better showing high specificity and low background ranged from 1,000-5,000.Works great also by western blot at dilutions 1:1,000-1:2,000.

  • Applications: Western Blot, Immunohistochemistry, Immunofluorescence
  • Primary Antibody Dilution: Wblot (1:1,000-2,000) IHC (1:1,500 - 1:5,000)
  • Cell Tissue Type: human cortex and spinal cord
