Cd274-KO(2)

Strain Name：C57BL/6Smoc-Cd274em2Smoc
Strain State：Repository Live | Cat. NO.：NM-KO-18044

Cd274 gene is also called B7-H1, Pdcd1lg1 or PD-L1. The PD-L1-KO(2) mouse model was obtained by deleting the Exon 3-5 region of mouse Cd274 gene. While PD-L1-KO(Stock No.NM-KO-00104) mice have been pulled from shelves for some reasons.

R26-pVillin1-hCYP3A4-IRES-tdTomato(FVB)

Strain Name：FVB-Gt(ROSA)26Sorem1(Gut-CYP3A4-IRES-tdTomato)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-18033

Intestinal expression of the CYP3A enzyme in the human body can cause significant intestinal metabolism of the compound, resulting in impaired drug absorption. This knock-in model was generated by inserting the human CYP3A4 cDNA driven by the Villin1 promoter together with the IRES-tdTomato reporter gene into mosue Rosa26 site, which can be crossed with the Cyp3a13 gene knockout and other Cyp3a family genes knockout mice to obtain intestinal-expressed CYP3A4 humanized mouse model in order to determine the contribution of intestinal metabolism to the absorption and distribution of test article.

Mice

Etv1-CreERT2

Strain Name：C57BL/6Smoc-Etv1em1(CreERT2-SV40-pA)Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KI-200105

A CreERT2 expression cassette was knocked into the Etv1 gene start codon site. ETV1 expression is enriched in fast conduction tissues of embryonic and adult mammalian hearts. And ETV1 expression is upregulated in the atrial tissue of patients with permanent atrial fibrillation. Etv-CreERT2 mice can be applied to heart disease research. ETV1 is also expressed in retinal ganglion cells of adult mice, and the mouse model can be used to study how retinal ganglion cells contribute to visual processing in the brain.

Mice

pMMTV-Jag1-Tg(Balb/c)

Strain Name：BALB/cAnSmoc-Tg(pMMTV-Jag1)2Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-TG-225004

These transgenic mice harbor pMMTV-Jag1 expression cassettes.

Mice

Foxj1-EGFP-CreERT2

Strain Name：C57BL/6Smoc-Foxj1em1(GFP-CreERT2-polyA)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-200133

A GFP-CreERT2-polyA expression cassette was knocked into the Foxj1 gene start codon site.

Mice

Zap70-W163C(Balb/c)

Strain Name：BALB/cAnSmoc-Zap70em(W163C)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-210366

These mice carry a W163C mutation of Zap70 gene.

Mice

KPC

Strain Name：C57BL/6Smoc-Trp53em4(R172H)Krasem4(LSL-G12D)Tg(Pdx1-cre)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-210096

The KPC mouse is an established and clinically relevant model of pancreatic ductal adenocarcinoma (PDAC) which develops many key features observed in human PDAC including pancreatic intraepithelial neoplasia alongside a robust inflammatory reaction including exclusion of effector T cells. Metastases are observed in around 80% of KPC animals located primarily in the liver and lungs. Mutations in both KRAS and TP53 genes are found in around 80% and 70% of all human PDACs respectively. Trp53-R172H、Kras-LSL-G12D were crossed with Pdx1-Cre-Tg to generate KPC mice. The KPC mouse contains a dominant negative point mutation in the transformation related protein 53 gene (TP53R172H), and a conditional activation point mutation in the KRAS gene (KRASG12D). A lox-stop-lox termination sequence is encoded upstream of KRAS mutated genes to prevent expression in the absence of Cre recombinase. The pancreas-specific Pdx-1 promoter enables expression of Cre recombinase in acini, islet and duct cells of the pancreas. Cre-mediated recombination excises the lox-stop-lox termination sequences and enables expression of KRASG12D in pancreatic tissue.

Mice

hIL18RAP/hIL18R1

Strain Name：C57BL/6J-Il18rap em1（hIL18RAP）Il18r1 tm1（hIL18R1）Smoc
Strain State：Developing | Cat. NO.：NM-HU-252777

The model was constructed based on hIL18R1,the endogenous mouse Il18rap gene was replaced by human IL18RAP gene.

Mice

R26-pAPOE-hCYP3A4(FVB)

Strain Name：FVB-Gt(ROSA)26Sorem1(pAPOE-CYP3A4)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-18032

This knock-in model was generated by inserting the human CYP3A4 cDNA driven by the liver-specific APOE promoter into the mouse Rosa26 site, which can be used to obtain liver-expressed CYP3A4 humanized model after mating with the Cyp3a13 gene and other Cyp3a family gene knockout mice. This model can be used with NM-KI-18033 mice which has gut-specific expression of human CYP3A4 to compare the contribution of intestinal versus hepatic metabolism to the biotransformation of a test article.

Mice

Cd8a-IRES-Luc-2A-EGFP

Strain Name：C57BL/6Smoc-Cd8aem1(V5-IRES-luci-2A-EGFP)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-18030

A V5-IRES-luci-2A-EGFP expression cassette was inserted before the stop codon TAA of mouse Cd8a gene to establish a multi-labeled knockin model with V5, luciferase and EGFP fluorescent protein.
