Human Tyrosyl-DNA Phosphodiesterase 1 (TDP1) ELISA Kit

Sample Types: serum, plasma, tissue homogenates, cell lysates Detection Range: 62.5 pg/mL-4000 pg/mL Sensitivity: 15.6 pg/mL Assay Principle: quantitative Measurement: SandwichAssay Time: 1-5h Sample Volume: 50-100ulDetection Wavelength: 450 nmProtein function: DNA 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.
