ABI
lity and translation efficiency prior to transferring into eukaryotic cells



CDN
A library construction using a primer containing poly(dT) on its 3? end.



Synthesis of polyadenylated RNA for nucleic acid amplification






Source

A recombinant
E. coli
strain carrying E. coli Poly(A) Polymerase gene



Unit Definition

1 unit is defined as the amount of enzyme that will incorporate 1 nmol of ATP into acid-insoluble material in 10 minutes at 37°C.



Components



Poly(A) Polymerase:
5,000 U/ml in 20 mM Tris-HCl, 300 mM NaCl, 1 mM DTT, 1 mM EDTA, 50% Glycerol, 0.1% Triton? X-100, pH 7.5 @ 25°C

10X Reaction Buffer
