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.

Gene tracking

marker gene gene tracking

Gene tracers are an important application for genetically engineered mice. Through gene knock-in, exogenous tracer genes were knocked into endogenous genes, enabling labeling and tracing of genes.

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.

Dysgenesis model

infertility diseases prss37 gene KO mice

Prss37 gene knockout infertility mouse model. SMOC has developed the Prss37 gene knockout mouse model (Prss37 KO, Model No.: NM -KO-00016) by ES cell targeting. It is a homozygous male infertility model.

P53 CKO Mouse Model

p53 knockout p53 knockout mice p53 gene

Our own-developed mouse model of p53 conditional knockout (p53-CKO) can be mated with mice carrying tissue-specific Cre expression to obtain mice with homozygous deletion of p53 in specific tissues or cells. These mice can be used for tumorigenesis and tumor mechanistic studies.

Pten CKO Mouse Model

Our own-developed mouse model of Pten conditional knockout (Pten-CKO) can be mated with mice carrying tissue-specific Cre expression to obtain mice with homozygous deletion of Pten in specific tissues or cells, thus avoiding the embryonic death caused by systemic and homozygous Pten knockout. Pten-CKO mice can be used to study tumorigenesis, anti-tumor targets, neurogenesis, glial differentiation and cerebellar development.
