Figure Lengend Snippet: Scheme of workflow to construct oligonucleotides for miRNAs (A) Workflow for construction of miRNA oligonucleotides using the BLOCK-iT ™ RNAi Designer (Invitrogen, https://rnaidesigner.thermofisher.com/rnaiexpress/ ) website. Several 21-mer-oligonucleotide sequences are automatically provided depending on the specificity for sequences of targeted genes (the sequences with “5 stars” are recommended as highly specific sequences). (B) Scheme of the contents in the annealed miRNAs for the targeted gene ( Setd1a as an example). The 64-mer oligonucleotides contain the linker sequence, the 21-mer sequence selected from the target gene, the loop sequence, and the 21-mer sequence excluding the 9th and 10th nucleotides. (C) Scheme of the process to insert the oligonucleotides into the pCAG-GFP empty vectors.
