Drosophila Targeted RNAi Service

Targeted RNA interference (RNAi) is a powerful genetic tool used in Drosophila melanogaster research to investigate gene function and manipulate gene expression. RNAi allows researchers to selectively silence or knockdown the expression of specific genes, providing valuable insights into their roles in various biological processes. CD BioSciences specialize in offering cutting-edge services in the field of Drosophila research. Our Drosophila Targeted RNAi Service leverages the power of RNA interference (RNAi) to enable precise genetic manipulation and investigation of gene function in Drosophila melanogaster.

Introduction to Drosophila Targeted RNAi

The principle of targeted RNAi in Drosophila research involves introducing synthetic siRNAs into the cells of the Drosophila melanogaster to silence the expression of a specific gene. This is typically achieved by injecting siRNAs into early-stage Drosophila embryos or by using genetic engineering techniques to generate transgenic flies expressing short hairpin RNAs (shRNAs), which are processed into siRNAs within the fly's cells. The siRNAs bind to their target mRNA molecules, triggering their degradation by an enzyme called Dicer, leading to a reduction or complete loss of the corresponding gene's expression.

In contrast to S2 cells, delivering dsRNAs into the Drosophila organism poses a challenge. To induce RNAi in Drosophila, libraries of fly strains bearing transgenes for the expression of hairpin type RNAs have been developed. Given that RNAi targeting essential genes can result in lethality, it is necessary to carefully control the expression of hairpin RNAs to ensure the stability of transgenic flies. Thus, in Drosophila, the Gal4/UAS system, commonly used to control gene expression, allows for the expression of dsRNA in target cells as hairpin RNA.
