Model organisms are instrumental to the study of gene functions. Gene editing technology has always played a crucial role in the research on gene functions, diseases and drug discovery, through its application in genetic engineering of model organisms, mimicking of human diseases, as well as observation of physiological or pathological changes. In particular, the CRISPR/Cas9 technology has achieved remarkable breakthroughs in recent years, significantly improving the efficiency of genetic engineering in model organisms, and facilitating more extensive and in-depth applications of animal models in various research fields.

Who We are

Type of genetic engineering

genetic modified organism types of genetic engineering genetic engineering technology

Three types of genetic modification by the gene engineered technology: gene knockout. gene knock-in, gene overexpression.

Gene Knock-in

gene knock in knock in mice knock in mouse

Knock-in represents the introduction of specific mutations or exogenous genes, such as point mutations (mimicking human genetic disease) at the selected location or reporter genes (e.g., EGFP, RFP, mCherry, YFP, LacZ, Luciferase etc.) or functional cDNAs (such as Cre, Dre etc.) into a specific genomic locus through homologous recombination, thereby allowing the exogenous DNA fragment to be expressed. A simultaneous occurrence of knock-in and knock-out can be achieved by replacing a murine endogenous gene with a foreign DNA fragment.
