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).22309-1-AP is a rabbit polyclonal 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.

FH Rashmi (Verified Customer) (09-25-2024) | Used for WB, Highly Recommended
|
FH Vikas (Verified Customer) (07-11-2024) | Used for western blotting. Highly recommended.
|
FH Madison (Verified Customer) (06-24-2024) | This antibody Stained well in the human tissue there were very clear phospho tangles and there was not a lot of nonspecific staining in the tissue.
|
FH MANOHAR (Verified Customer) (03-06-2024) |
|
FH Shenyi (Verified Customer) (04-27-2022) | Staining with this antibody is very different from with the recombinant one (80007-1-RR) which I received as a free test vial. It showed strong signal in the nucleus while the recombinant one only showed signal in the cytoplasm. Now I'm confused: Could pTDP-43 (Ser409/410) also present in nucleus or it's the antibody being nonspecific?

FH Laura (Verified Customer) (01-10-2020) | Works well at this concentration on HEK293T lysate.
|
FH Owen (Verified Customer) (10-30-2019) | This antibody was used to image TDP43 in tissue and cell samples. The antibody was useful to image such a difficult target.
