Abstract
Adapted from the protocol for oligonucleotide 5′ adenylation (E2610) of New England Biolabs (NEB).
Materials
MATERIALS
Reagent5’ DNA Adenylation Kit - 10 rxnsNew England BiolabsCatalog #E2610S


Mix the following components (20 μL):

ComponentAmount [μL]Final concentration
5′ phosphorylated DNA oligo [50 μM]410 μM
10× 5′ DNA Adenylation buffer2
ATP [1 mM]20.1 mM
Mth RNA ligase [50 pmol/µL]410 µM
RNase-free water (ddH2O)8


Incubate for 60 minutes at 65 °C.
Incubate for 5 minutes at 85 °C to inactivate the enzyme.
The adenylated oligo can be directly used for RNA ligation with T4 RNA ligase 2 (optimally with T4 RNA Ligase 2, truncated KQ (NEB #M0373)).
