일반 설명

Native TdT from calf thymus. Tdt is a DNA polymerase that catalyzes the addition of deoxynucleotides to the 3′ hydroxy terminus of either double of single stranded DNA in a template-independent manner.

Native TdT from calf thymus. Tdt is a DNA polymerase that catalyzes the addition of deoxynucleotides to the 3′ hydroxy terminus of either double of single stranded DNA in a template-independent manner. Although TdT preferentially adds deoxynucleotides to 3′-extensions, tailing onto 5′ overhangs or blunt ended double strands of DNA can also be achieved. TdT can be used for labeling DNA fragments and vectors with homopolymer tails and/or with modified deoxynucleotides such as biotin-dNTPs, ³²P-dNTPs, cordycepin-dNTPs, or ddNTP.

The Calbiochem^® Terminal deoxynucleotidyl Transferase (TdT) is a DNA polymerase isolated from calf thymus. TdT catalyzes the addition of deoxynucleotides to the 3′-hydroxyl termini of either double or single stranded DNA molecules in a template independent manner. Although TdT preferentially adds deoxynucleotides to 3′-extensions, tailing onto 5′ overhangs or blunt ended double strands of DNA can also be achieved. TdT can be used for labeling DNA fragments and vectors with homopolymer tails and/or with modified deoxynucleotides such as biotin-dNTPs, 32P-dNTPs, cordycepin-dNTPs, or ddNTP.
