Poly(A) Polymerase, Yeast
| Cat. No. | E017 |
| Name | Poly(A) Polymerase, Yeast |
| Unit | 100 U (100 μl) |
| Category | Molecular Biology Enzymes and Kits |
| Description |
Poly(A) Polymerase, Yeast catalyses the template independent addition of adenosine residues onto the 3' ends of polyribonucleotides. The use of ATP as a substrate leads to poly(A) tailing whereas substitution of cordycepin-5'-triphosphate (3'-dATP) for ATP results in addition of a single dA residue to the 3’-termini of the RNA. Neither ADP nor dATP can be used as substrates for this enzyme. Poly(A) Polymerase from yeast has been shown to be more effective at oligonucleotide-labeling and poly(A) tailing of long RNA templates than Poly(A) Polymerase from E. coli. |
| Application |
• Labelling of RNA with ATP or cordycepin |
| Concentration | 1 U/μl |
| Components | Enzyme supplied with 5X Reaction Buffer. |
| Storage Buffer | 20 mM Tris-HCl (pH 8.0), 100 mM NaCl, 0.1 mM EDTA, 1 mM DTT, 0.1% Triton® X-100 and 50% (v/v) Glycerol. |
| Storage Condition | Store all components at -20°C. |
| Note |
One unit is defined as the amount of Poly(A) Polymerase, Yeast that catalyzes the incorporation of 1 nmol of AMP into RNA in 10 minutes at 37°C. |
