Specifications and Other Information of Our Poly(A) Polymerase CAS 9026-30-6

Product Introduction

This product is the Poly(A) Polymerase recombinantly expressed in E. coli. It catalyzes with ATP as the substrate, and adds adenyl acid to the 3’-hydroxyl terminus of RNA to form the PolyA tail structure in the form of AMP.

Product Features

Efficient mRNA capping: adding 200nt polyA tail to 10μg of RNA in 10min (5U enzyme for capping). Homogenous tailing length: controlling polyA tail length by adjusting reaction time or enzyme dosage.
