Detailní popis

Thermo Scientific T4 RNA Ligase catalyzes the ATP-dependent intra- and intermolecular formation of phosphodiester bonds between 5'-phosphate and 3'-hydroxyl termini of oligonucleotides, single-stranded RNA and DNA.

The minimal substrate is a nucleoside 3',5'-biphosphate in intermolecular reaction and oligonucleotide of 8bases in intramolecular reaction.


  • RNA 3'-end labeling with cytidine 3',5'-bis [alpha-32P] phosphate (seeReference1)
  • Joining RNA to RNA(seeReference2)
  • Synthesis of oligoribonucleotides and oligodeoxyribonucleotides(seeReferences 3, 4)
  • Specific modifications of tRNAs(seeReference5)
  • Oligodeoxyribonucleotide ligation to single-stranded cDNAs for 5' RACE (Rapid Amplification of cDNA Ends)(seeReference6)
  • Site-specific generation of composite primers for PCR(seeReference7)


The recommended BSA concentration in the reaction mixture is 0.1mg/mL.

10X Reaction Buffer 500mM Tris-HCl (pH7.5 at 25°C), 100mM MgCl2, 100mM DTT, 10mM ATP
