Popular Model Organisms

genetically modified organisms transgenic organisms genetically modified organisms examples

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.

Gene Knockout

Expedite your research with highly customizable, gene knockout mouse models that provide thorough insight into key genetic mechanisms.

Mouse

transgenic mice mouse model editing mouse

Mice have long been the prime choice for model organisms. In more than 100 years, mice have been widely used by researchers in the fields of physiology, pathology, pharmacology, toxicology, and behavioral science. With the establishment of gene targeting technology, many researchers have made their way to the Nobel Prize.

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.

U-GEMM Repository

The U-GEMM Repository has more than 6000 Genetically Engineered Mice & Rat Models, including KO , Flox，Cre/Dre, gene humanized knockin, Immunodeficiency, reporter Knockin , genetic disease and other models. You can Search for Mouse & Rat Models by Name, Catalog Number or Keyword.

The laboratory mouse is widely considered as a valid and affordable model organism for studying human disease. Mouse models of cancer not only enable researchers to understand the genetic basis of tumor development in complicated and dynamic physiological systems, but also serve as irreplaceable tools for developing and testing new therapies.  Shanghai Model Organisms Center offers a variety of mouse models of cancer to meet the needs of both academic and industry partners.

Lineage tracing
