| Description |
S. pombe Poly(U) (Poly(A)) Polymerase uses ATP as a substrate for template-independent addition of UMP from UTP or AMP from ATP to the 3´ hydroxyl termini of RNA molecules.
|
| Applications |
- Labeling of RNA with UTP
- Poly(U) and Poly(A) tailing of RNA for cloning
- Enhance mRNA stability and increase translation efficiency of in vitro synthesized mRNA transferred into eukaryotic cells
- Poly (A) tailing of 2' O-Me modified 3' ends
