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). 60019-2-Ig is a mouse monoclonal antibody recognizing the cleavage product of 20-30 kDa in addition to the native and phosphorylated forms of TDP-43. Immunohistochemical analyses of TDP-43 using this antibody detect both normal diffuse nuclear staining and insoluble inclusions in pathologic tissues. Notably this antibody only recognizes human TDP-43 but not reacts with mouse or rat TDP-43.

Reviews
What customers say
Both reviewers gave this antibody a perfect 5-star rating. One user reported excellent performance in Western blot on neuroblastoma cell lines (SK-N-BE(2)C and IMR32) at 1:2000 dilution, and also successfully used it at 1:50 for a Proximity Ligation Assay to assess protein interactions. The second user praised its versatility across multiple applications, noting it works well for immunoblotting (1:1000), immunofluorescence (1:500), and RNA immunoprecipitation (30 µg) in SH-SY5Y cells. Overall, users highlight strong specificity, reliable signal, and broad application compatibility.

Lidiya (Verified Customer) (05-26-2022) | The antibody works great! Antibody was used for WB in Neuroblastoma cell lines (SK-N-BE(2)C and IMR32) with HRP-conjugated secondary. Antibody was also used for a Proximity Ligation Assay to assess interaction with another protein in SK-N-BE(2)C cells. 1:50 of antibody was used for this assay.
