T4 RNA Ligase (10 U/μL) (Thermo Scientific™)

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.

Applications

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

Note

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