Drosophila Cell RNAi Screening

Drosophila cell lines easily absorb dsRNA and are suitable for high-throughput functional genomic analysis by RNAi. Large-scale RNAi reduces mRNA transcript levels by specific shRNA or siRNA libraries. Not only has it been successfully used to study mitosis, cellular autophagy and cancer signaling, but it has also contributed to the development of Drosophila as a tool for personalized medicine. However, there are technical challenges to achieving efficient mRNA knockdown levels, and our professional services save you valuable time and resources and give you confidence in your data.

CD BioSciences has an experienced and dedicated scientific team to break through the data analysis barriers, and provides you with fast turnaround and high-quality data reports. To improve efficiency and extend knock-down duration, we recommend transfection of dsRNA/shRNA expression constructs. Our extensive database supports a variety of Drosophila cell lines for functional genomic screening, including the Schneider lines, Kc167, ML-BG2 and Cl.8, etc. For complex physiological process research objectives, we support the use of several cell lines to obtain different gene expression profiles, comparatively analyze the regulation of cellular processes, and identify functionally similar or related genes.
