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). 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. (17023659,19823856,21666678,22193176)
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)

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive forproviding their feedback.
FH Xiaochen (Verified Customer) (11-11-2024) | sensitive and specific
 |
FH Scott (Verified Customer) (10-22-2024) | 10µg of protein was loaded and antibody was incubated overnight at 4oC following a total protein stain. The band appeared at the expected size, blue bar, with Alpha-tubulin internal control (red band - 66031-1-Ig). Precision plus protein standard ladder #1610373.

FH Parijat (Verified Customer) (09-10-2023) | Good antibody
 |
FH Xin (Verified Customer) (01-23-2022) | Good performance in WB (around 45 kD)
 |
FH 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.
|
FH Jacob (Verified Customer) (03-25-2021) | Good for IF staining. It worked for cells fixation with 4% PFA.
 |
FH David (Verified Customer) (01-14-2020) | Good for both immunofluorescence and immunoblotting. Single band in control cells in the latter, but can detect stress induced C-terminal fragments.
