The DTdT-overhanging 19 nt RNA duplexes are short, double-stranded RNA molecules with 19 nucleotide sequences and 2-nucleotide overhangs at the 3' ends. These duplexes are designed for various applications in molecular biology and cell biology research.
The small-molecule inhibitors were SMIFH2 (Sigma s4826, 60 microM), CK-869 (Sigma C9124, 80 microM) LatrunculinA (Sigma L5163, 0.5 microM), G2 (Xcessbio M60269 for cell treatments, Valuetech custom synthesis for mouse injections). All plasmids were sequence-verified before use and transfected as endotoxin-free maxi preps. siRNAs were selected among FlexiTube GeneSolution 4 siRNA sets (Qiagen) and reordered after validation as dTdT-overhanging 19 nt RNA duplexes (Thermo). shRNAs were selected among pre-validated Mission pLKO1-shRNA (Sigma) and the corresponding U6-shRNA-cPPT cassettes were subcloned into PB-empty vector25 (link). Sequences of siRNAs are provided in Table 1.

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
