商品信息

Description:
Thermo
stable 5? App DNA/RNALigase is a point mutant of catalytic lysine of RNAligase from
Methanobacterium
Thermo
autotrophicum
(1). This enzyme is ATP independent. Itrequires a 5? pre-adenylated linker for ligation tothe 3?-OH end of either RNA or single strandedDNA (ssDNA). The enzyme is also active in ligationof RNA with 2?-O-methylated 3? end to 5?-adenylatedlinkers (1). The optimal temperature forligation reaction is 60–65°C (2). The mutant ligaseis unable to adenylate the 5?-phosphate of RNA orssDNA, which reduces the formation of undesiredligation products (concatemers and circles).
The
ABI
lity of the ligase to function at 65°C mightreduce the constraints of RNA secondary structurein RNA ligation experiments.

Notes:
For optimal ligation of ssDNA toadenylated DNA linkers, we recommend using
NEB
uffer 1 supplemented with manganese. Forligation of ssRNA to adenylated DNA linkers, justuse
NEB
uffer 1. Heat inactivation or Proteinase Ktreatment is required to release RNA bound by theligase.
