Descrizione generale

Bovine terminal transferase (TdT) is a primer-dependent polymerase that catalyzes the addition of deoxynucleotides to the 3′-OH terminus of DNA molecules with the release of inorganic phosphate. TdT reacts preferentially with either single-stranded DNA molecules or double-stranded-DNA with 3′ overhangs, but procedures have been developed to label blunt ends or 3′-recessive ends. In a reaction mixture, the divalent ion (Co2+, Mn2+, Mg2+) will influence purine and pyrimidine polymerization rate. Activities of TdT are also affected by the bases (dATP, dCTP, dGTP and dTTP) present.

Applicazioni

Suitable for:
  • Addition of homopolymers to vectors, inserts and cDNA for cloning
  • Labeling the 3′-end of double- and single-stranded DNA with non-radioactive or radioactive labels
  • Carrying out in vitro mutagenesis by adding single nucleotides to DNA
  • Use in TUNEL assays

Componenti

Terminal transferase is supplied as a solution of 50 mM potassium phosphate (pH 7.4), 1 mM 2-mercaptoethanol and 50% glycerol (v/v).

Definizione di unità

One unit will incorporate 1 nanomole of dATP into acid-precipitable material in one hour at 37 °C using d(pT)6 as primer.

Risultati analitici

Activity assay uses 200 mM potassium cacodylate, pH 7.2, 4 mM MgCl2, 1 mM 2-mercaptoethanol, 1 mM 3H-dATP, 70 μM d(pT)6, 37 °C.

Apoptosis of cardiomyocytes may contribute to ischemia-reperfusion injury. The role of nitric oxide (NO) in apoptosis is controversial. Therefore, we investigated the effect of NO synthase inhibition on apoptosis of cardiomyocytes during ischemia and reperfusion and elucidated the underlying mechanisms.

Although the definition of precursor T lymphoblastic lymphoma (T-LBL) is based only on histopathology, most cases cannot be diagnosed only by HE sections. Since 95% of T-LBL expresses TdT and TdT is expressed only in lymphoblasts, immunohistochemical demonstration of TdT
