Opis ogólny
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.
Zastosowanie
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
Komponenty
Terminal transferase is supplied as a solution of 50 mM potassium phosphate (pH 7.4), 1 mM 2-mercaptoethanol and 50% glycerol (v/v).
Definicja jednostki
One unit will incorporate 1 nanomole of dATP into acid-precipitable material in one hour at 37 °C using d(pT)6 as primer.
Komentarz do analizy
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.

Acute lymphoblastic leukemia (ALL) is the most common type of childhood cancer, presenting with approximately 5,000 new cases each year in the United States. An interesting enzyme implicated in this disease is terminal deoxynucleotidyl transferase (TdT), a specialized DNA polymerase

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.

Cordycepin-5'-triphosphate (3'-deoxyadenosine-5'-triphosphate) can be incorporated into the 3'-ends of DNA fragments using terminal deoxynucleotidyl transferase from calf thymus (Bollum, 1974). Because cordycepin-5'-monophosphate lacks a 3'-OH group, only a single residue is incorporated. Furthermore, DNA molecules that contain cordycepin-5'-monophosphate at their

Secondary rearrangements of the T cell receptor (TCR) represent a genetic correction mechanism which changes T cell specificity by re-activating V(D)J recombination in peripheral T cells. Murine T-cell hybridoma A1.1 was employed to investigate whether antigenic stimulation induced re-expression of
