form |
The A-Plus™ Poly(A) Polymerase Tailing Kit uses ATP as a substrate for template-independent additionof adenosine monophosphates to the 3'-hydroxyl termini of RNA. The standard prot°Col produces apoly(A)-tail length of ~150 b on 40-60 μg of RNA.Polyadenylation increases the stability of RNA ineukaryotic cells and enhances its ability to be translated after transfection or microinjection.1-3 A Poly(A)tail is useful to provide a priming site for first-strand cDNA synthesis in certain applications, and can beused to end-label4 or quantify5 mRNA.
