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). 12892-1-AP is a rabbit polyclonal antibody raised against the C-terminal amino acids of human TDP-43. This antibody recognizes 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. Various forms of TDP-43 exist, including 18-35 kDa of cleaved C-terminal fragments, 45-50 kDa phosphoprotein, 55 kDa glycosylated form, 75 kDa hyperphosphorylated form, and 90-300 kDa cross-linked form.

Recently TDP-43 has been reported to be overexpressed in triple negative breast cancer (TNBC) and it may be a potential target for TNBC diagnosis and drug design. (29581274)

Xin (Verified Customer) (01-23-2022)
Good performance in WB (around 45 kD)
Azita (Verified Customer) (06-17-2021)
Immunocytochemistry labelling of (4% PFA) fixed NSC-34 cells by TDP-43 (C-terminal) Polyclonal antibody at dilution of 1:500 showed strong labelling.
Jacob (Verified Customer) (03-25-2021)
Good for IF staining. It worked for cells fixation with 4% PFA.
David (Verified Customer) (01-13-2020)
Good for both immunofluorescence and immunoblotting. Single band in control cells in the latter, but can detect stress induced C-terminal fragments.
Alinda (Verified Customer) (02-28-2019)
Noemi (Verified Customer) (01-24-2019)
really good antibody, it detects also the cleavage product of TDP43 in WB.
