MicroRNAFirst, a miRNA-specific stem-loop RT primer is hybridized to the miRNA and then reverse transcribed. Convert miRNA sequence to a DNA sequence 2. to reduce unspecific staining after hybridization you could use RNase A to remove unbound probe (also removing un-incorporated nucleotides by column purification could help) quality of the RNase. This mechanism is orders of magnitude faster than others proposed for the de novo creation of genes, enabling near-instant rewiring of genetic information and rapid adaptation to changing environments. These duplexes interact with the argonaut proteins (AGO) and bind the RISC complex where one strand is selected as the mature miRNA (Fig. . ADAR-mediated conversion of adenosine to inosine allows inosine:cytosine pairing because inosine is chemically similar and functionally equivalent to guanosine (Fig. >> Show all products1). ** This is a software tool to create a scrambled sequence as negative control for your siRNA experiment. 33% and 62. 1007/978-1-60761-863-8_15.
