Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Use at an assay dependent dilution.
機能DNA polymerase specifically involved in DNA repair. Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Depending on the context, it inserts the correct base, but causes frequent base transitions, transversions and frameshifts. Lacks 3'-5' proofreading exonuclease activity. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but does not have lyase activity.
組織特異性Detected at low levels in testis, spleen, prostate and ovary. Detected at very low levels in kidney, colon, brain, heart, liver, lung, placenta, pancreas and peripheral blood leukocytes.
配列類似性Belongs to the DNA polymerase type-Y family. Contains 2 UBZ-type zinc fingers. Contains 1 umuC domain.
ドメインThe catalytic core consists of fingers, palm and thumb subdomains, but the fingers and thumb subdomains are much smaller than in high-fidelity polymerases; residues from five sequence motifs of the Y-family cluster around an active site cleft that can accommodate DNA and nucleotide substrates with relaxed geometric constraints, with consequently higher rates of misincorporation and low processivity.
細胞内局在Nucleus. Detected throughout the nucleus and at replication foci.
ab115625, at 5 µg/ml, staining DNA Polymerase Kappa/POLK in formalin fixed, paraffin embedded Human prostate tissue by Immunohistochemistry. Following primary incubation slides were incubated with biotinylated anti-goat IgG secondary antibody, alkaline phosphatase-streptavidin and chromogen.
