Applications

Our Abpromise guarantee covers the use of ab4166 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use at an assay dependent concentration.
ICC/IF Use at an assay dependent concentration. PubMed: 21041670
WB Use a concentration of 1 µg/ml. Detects a band of approximately 75 kDa (predicted molecular weight: 68 kDa).

Abcam recommends blocking with 1-3% Milk.

IHC-P 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. 20 min in boiling Tris-EDTA solution, see Abreview by Frédéric Leduc.

Target

  • FunctionDNA repair enzyme that can remove a variety of covalent adducts from DNA through hydrolysis of a 3'-phosphodiester bond, giving rise to DNA with a free 3' phosphate. Catalyzes the hydrolysis of dead-end complexes between DNA and the topoisomerase I active site tyrosine residue. Hydrolyzes 3'-phosphoglycolates on protruding 3' ends on DNA double-strand breaks due to DNA damage by radiation and free radicals. Acts on blunt-ended double-strand DNA breaks and on single-stranded DNA. Has low 3'exonuclease activity and can remove a single nucleoside from the 3'end of DNA and RNA molecules with 3'hydroxyl groups. Has no exonuclease activity towards DNA or RNA with a 3'phosphate.
  • Tissue specificityUbiquitously expressed. Similar expression throughout the central nervous system (whole brain, amygdala, caudate nucleus, cerebellum, cerebral cortex, frontal lobe, hippocampus, medulla oblongata, occipital lobe, putamen, substantia nigra, temporal lobe, thalamus, nucleus accumbens and spinal cord) and increased expression in testis and thymus.
  • Involvement in diseaseSpinocerebellar ataxia, autosomal recessive, with axonal neuropathy
  • Sequence similaritiesBelongs to the tyrosyl-DNA phosphodiesterase family.
  • Post-translational
    modifications
    Phosphorylated on serine and/or threonine residues, but not on tyrosine residues.
  • Cellular localizationNucleus. Cytoplasm.

  • ab4166 staining TDP1 in MCF-7 cells by Immunocytochemistry/ Immunofluorescence.
    Briefly, cells were incubated in medium containing 100 nM Mitotracker Red 580 (red) at 37 °C for 30 minutes and fixed with 4% paraformaldehyde. Primary antibody against TDP1 was detected with anti-rabbit IgG secondary antibodies labeled with Alexa 488 (green). Nuclei were stained with DAPI (blue).
