U6-shRNA-GFP AAV (Serotype 2)

U6-shRNA-GFP AAV (serotype 2) is a recombinant adeno-associated virus (AAV) vector specifically tailored for gene silencing research applications. This vector is engineered from serotype 2 of the AAV family to express random short hairpin RNAs (shRNAs) driven by the U6 promoter. It also co-expresses green fluorescent protein (GFP) as a reporter gene under the control of a cytomegalovirus (CMV) promoter.

The U6 promoter is known for its strong and ubiquitous expression in mammalian cells, making it an ideal driver of small hairpin RNA (shRNA) transcription. shRNAs are designed to be complementary to specific messenger RNA (mRNA) targets, thereby achieving RNA interference (RNAi). This RNAi mechanism effectively silences the expression of a target gene by promoting the degradation of its mRNA, thereby preventing the translation and production of the protein associated with that gene. The primary application of this AAV construct is as a control in gene knockdown experiments. By using random shRNAs, which do not target any specific mRNA within the host system, researchers can effectively demonstrate that changes observed in experimental outcomes are specific to the knockdown of their gene of interest and are not off-target or accidental results.
