1,000 units, 5,000U/ml

Poly(A) Polymerase catalyzes the addition of AMP from ATP to the 3'-hydroxyl of RNA. The reaction requires Mg2+ and is template independent.

- Labeling of RNA with ATP or cordycepin
- Poly(A) tailing of RNA for cloning or affinity purification
- Enhances translation of RNA transferred into eukaryotic cells
