Recombinant Poly(A) Polymerase
Cat No.
COV-014
Description
This product is a polymerase expressed by recombinant E.coli. The enzyme does not depend on the template and can catalyze the sequential incorporation of ATP into the 3′ end of RNA in the form of AMP, that is, adding a polyadenosine tail to the 3′ end of RNA. Poly(A) structure can improve the stability of RNA and improve the translation efficiency of mRNA in eukaryotic cells. Poly(A) polymerase has high tailing efficiency and can add 20-200 A bases to the 3′ end of RNA.
Source
