WebApr 20, 2009 · both is possible, just make sure that if the product spans the exon/exon junction that the intron between is big enough that it cant be amplified in PCR during elongation. eg. a 100bp intron would be coamplified, a 10kb intron rather not. you can also use this to see if you have gDNA in your RNA preparation. design primers for a HKG on ...

WebMay 25, 2024 · Author summary The Exon Junction Complex (EJC) is a conserved multiprotein complex that is deposited ~20–24 nucleotides upstream of exon-exon junctions during mRNA splicing. Although the EJC is well-conserved, many of its overt regulatory requirements differ between species. For example, the mammalian EJC is … Webprimers somehow amplify gDNA. 2.) the primer that sits on an exon-exon junction should not anneal, as the transcript will have undergone splicing, such that introns are removed, allowing for the primer to sit down at its appropriate location within the mature transcript. 7.
