描述:

末端核苷酸转移酶,重组

Terminal Deoxynucleotidyl Transferase, Recombinant (rTdT) is a DNA polymerase that catalyzes the addition of deoxynucleotides to the 3fi hydroxyl terminus of DNA. A TdT Technical Bulletin is available.

Applications: Homopolymer tailing of vector and insert for cloning. Labeling oligonucleotides with biotin (1,2), 32P- or 35S-label (3), or in apoptosis (TUNEL) (4,5).

Source: Purified from a baculovirus clone of calf thymus TdT.

Performance and Quality Testing: Endonuclease, 3´ and 5´ exodeoxyribonuclease, and levels of incorporation tested.

Unit Definition: One unit incorporates 1 nmol dATP into acid-precipitable material in 1 h at 37°C, using d(pA)50 as a primer.

Hazard Warning: Toxic; potassium cacodylate contained in reaction buffer. Also contains cobalt chloride, a highly toxic chemical.
See MSDS.

Unit Reaction Conditions:

0.2 M potassium cacodylate (pH 7.2), 10 mM MgO4 C4 H6 , 1 mM 2-mercaptoethanol, 0.5 mg/ml BSA,
100 flM d(pA)50, 1 mM [3H]dATP, and enzyme in 0.15 ml for 1 h at 37°C.


注意事项:

For Research Use Only. Not for use in diagnostic procedures.
