Dcas9 knockdown
Traditionally, there have been two major approaches to decreasing gene expression transiently that involve using RNA to base-pair with host RNA. Although successful, these methods have been challenging, as it is difficult to find a good RNA sequence which interferes strongly with the desired target and not with … See more Antisense oligonucleotides(ASOs) are DNA oligos, typically 15–25 bases long, designed in antisense orientation to the RNA of interest. Hybridization of the ASO to the target RNA mediates RNase H cleavage of the RNA, … See more CRISPR is widely known as a tool useful for complete gene knockout. However, there are also three major ways in which CRISPR can be used to cause transient gene knockdown. These approaches are as follows: See more
