Product Overview
Clone ABAB-20 is a rabbit monoclonal antibody that recognizes TAR DNA-binding protein 43 (gene TARDBP) in human, mouse, rat and zebrafish samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 44.7 kDa, and the supplier reports an observed band at about 40 kDa.
TDP-43 (TARDBP) is a nuclear RNA-binding protein with two RRM domains that binds GU-rich sequences to regulate splicing, mRNA stability and transport. Cytoplasmic aggregates of TDP-43 are a pathological hallmark of most ALS cases and of frontotemporal lobar degeneration, making it a central protein in neurodegeneration research.

Immunogen
Synthetic peptide based on the sequence of human TDP43.
Reactivity Notes
The supplier lists reactivity with human, mouse, rat and zebrafish. UniProt places TAR DNA-binding protein 43 in the nucleus, cytoplasm and mitochondrion. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
