Dear all,
I have generated Stable Cell lines via G418 selection.
I have used pCMV-miR vector.Except Neo-GFP region, my chance is 2/5 to integrate genome without damaging CMVpromotor-insert-PolyA tail region.
So my question is that;
Can I try to detect PolyA tailed pri-miRNA forms by oligodT cDNA synthesis. Due to overexpression, as far as I am concerned I should.
and the second question is that, if my PolyA signal is destructed during integration, ( I can check via genomic pcr CMVpromotor to insert) can this destruction effect miRNA expression? Normally miRNAs do not require polyA signal for biogenesis but they require correct transcriptional termination.
