In vitro and cell culture studies indicate that plasmids containing the SV40 and the synthetic poly A sequences present significant improvements in nuclease resistance (up to two-fold increase in half-life). However, RT-PCR analysis demonstrated that significant reduction in mRNA steady-state levels … Out of those listed, the SV40 late polyA and rbGlob polyA are thought to be more efficient in terminating transcription due to the presence of additional helper sequences (2-3). As alluded to above, termination and polyadenylation of Polymerase II transcripts (and therefore mRNAs) are coordinated processes. In vitro and cell culture studies indicate that plasmids containing the SV40 and the synthetic poly A sequences present significant improvements in nuclease resistance (up to two-fold increase in half-life).

In the present study, the SV40 polyA was inserted downstream of the polyhedrin promoter in many baculovirus expression vector systems (BEVSs) (Salem et al., 2015). Additionally, the SV40 polyA was inserted SV40 PolyA (Simian virus 40 PolyA, also called PolyA) sequence is DNA sequence (240 bp) that possesses the activity of transcription termination and can add PolyA tail to mRNA. PolyA contains AATAAA hexanucleotide polyadenylation signal.

But is transcription of transcipt 2 (an antisense transcript) terminated at all, or maybe with lower efficiency? Could transcript 2 provide an antisense RNA for transcript 1, 2015-12-14 (2015) Salem et al. PLoS ONE. The simian virus 40 polyadenylation signal (SV40 polyA) has been routinely inserted downstream of the polyhedrin promoter in many baculovirus expression vector systems (BEVS).
