Poly(A) Polymerase, Yeast

商品詳情參考文獻(xiàn) 相關(guān)資料

	Print Version
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.
Components	Enzyme supplied with 5X Reaction Buffer.
Application	? Labelling of RNA with ATP or cordycepin ? Poly(A) tailing of RNA for cloning or affinity purification ? Increasing translation of RNA transferred into eukaryotic cells

Concentration	1 U/μl
Storage	Store all components at -20°C.
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.
Notes	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. This product is distributed for laboratory research only. Caution: Not for diagnostic use .
