T4 RNA Ligase 2 (truncated) (RNL2)
T4 RNA Ligase 2 (truncated) (RNL2)

MCLAB’s truncated  T4 RNA Ligase 2 was developed specifically for demanding Next-Generation RNA Sequencing applications.  The truncated  ligase 2 specifically ligates the adenylated 5´ end of an adapter to the 3´ end of RNA. The enzyme does not require ATP for ligation but does need an adenylated substrate. By not having an extra ATP in the reaction it dramatically reduces the amount of ligation between random RNA molecules.

Description:
MCLAB’s truncated T4 RNA Ligase 2 was developed specifically for demanding Next-Generation RNA Sequencing applications. The truncated ligase 2 specifically ligates the adenylated 5'-end of an adapter to the 3'-end of RNA. The enzyme does not require ATP for ligation but does need an adenylated substrate. By not having an extra ATP in the reaction, the amount of ligation between random RNA molecules is dramatically reduced. Unlike the full length T4 RNA ligase 2, the truncated ligase does not ligate the phosphorylated 5'-end of RNA or DNA without the adenylated substrate, making it an excellent choice for small RNA library preparation. Whether your plan to sequence miRNAs or to perform directional mRNA-Seq, the truncated ligase 2 will help to enhance your library preparations.
