The distance between the first 88 poly(A) site and the distal, vector poly(A) site is 612 nt. The distance between 88 sites is 160 nt. SV40 intron contains only 99nt and has been found to increase splicing efficiency and transport much more efficient mRNA 40-42. In this study, SV40 intron positioned downstream of the expression cassette results in highest transgene expression, this result may be relative to the function of cryptic splicing, increasing the poly A tail‐length, increasing the half‐life of mRNA and The simian virus 40 polyadenylation signal (SV40 polyA) has been routinely inserted downstream of the polyhedrin promoter in many baculovirus expression 2002-10-03 · C1 is between the EGFP coding sequences and the SV40 poly A. Genes cloned into the MCS will be expressed as fusions to the C-terminus of EGFP if they are in the same reading frame as EGFP and there are no intervening stop codons.

The multiple cloning site contains a range of standard commonly used restriction sites for cloning. 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. trxn termination sequence: hGH trxn term: human growth hormone gene transcription termination sequence: 0: 0: poly-A signal: hGH polyA: human growth hormone polyadenylation signal sequence: 0: 0: viral origin: SV40 ori: SV40 origin of DNA replication and early region enhancer sequences: 0: 0: bacterial origin: unknown ori: unknown bacterial The simian virus 40 polyadenylation signal (SV40 polyA) has been routinely inserted downstream of the polyhedrin promoter in many baculovirus expression 2007-12-19 1996-12-01 1981-04-01 Abstract. Polyadenylation [poly(A)] signals (PAS) are a defining feature of eukaryotic protein-coding genes.
