Drosophila belongs to the group of small flies with a body length between 1.5 and 4 mm. The body is mostly yellowish-brown, but some are black. The head has a pair of large, mostly bright red compound eyes.
Drosophila has a high degree of genetic similarity to mammals, while it is relatively simple yet can perform complex behaviors, and has been used extensively in genetic and developmental biology studies, making it an ideal model organism for research.
Drosophila melanogaster, the representative species of Drosophila, is widely used in genetic studies. Drosophila melanogaster is a dipteran insect with a short life history, easy rearing, fast reproduction, few chromosomes, many mutant types, and small individuals, making it an excellent material for genetic experiments and a commonly used model organism.

Gene knockout is a classical reverse genetics approach. To obtain efficient and heritable Drosophila mutants, Lifeasible uses CRISPR/Cas9 technology combined with Homology Directed Repair (HDR) strategy to edit the Drosophila genome, which can knock out target genes or introduce molecular modifications according to design. Our CRISPR/Cas9 system-based gene-editing technology offers the advantages of being simple and specific, efficient and cost-effective.

We use CRISPR/Cas9 not only for targeted gene knockout but also for other applications such as conditional knockout of genes, large fragment knockout of genes, CRISPRi, etc. conveniently.
Using gene-editing technologies such as CRISPR/Cas9, Lifeasible enables a variety of precise edits to the Drosophila genome, including:
