Sirt3-Flox

Strain Name：C57BL/6Smoc-Sirt3tm1(flox)Smoc
Strain State：Repository Live | Cat. NO.：NM-CKO-190039

These mice carry loxP sites flanking exon4 of Sirt3 gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of Sirt3 gene.

Mice

Lep-KO

Strain Name：B6;129S-Leptm1Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KO-00034

Exon 2 was replaced by Neo cassette.

Mice

Ucp2-KO

Strain Name：B6;129S-Ucp2tm1Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KO-00038

Homozygous null mutants may have elevated pancreatic islet cell ATP levels and increased glucose-stimulated secretion of insulin.

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

Rag1-KO(Rag1-EGFP)

Strain Name：B6;129S-Rag1tm1(loxP-EGFP-PolyA-loxP-Neo-loxP)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-00069

A loxP-EGFP-PolyA-loxP-Neo-loxP expression cassette was knocked into the Rag1 gene start codon site. As a Rag1 knockout mouse model, this stain can be used in subcutaneous inoculation of liver cancer tissues and tumor cells. Tumors can esaily form and grow. The amount of T and B lymphocytes in peripheral blood of mice was extremely low tested by FACS, which was comparable to or lower than that of Nude mice, and there was a significant difference compared with wild type mice. The pathological sections of HE staining of tumor tissues showed that the tumor sections of Rag1 KO mice and Nude mice were similar. This strain has the potential to replace Nude, NOD-SCID mice as a tumor-bearing mouse model.

Mice

Rag2-KO(Rag2-EGFP)

Strain Name：B6;129S-Rag2tm1(loxP-EGFP-PolyA-loxP-Neo-loxP)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-00070

A loxP-EGFP-PolyA-loxP-Neo-loxP expression cassette was knocked into the Rag2 gene start codon site. As a Rag2 knockout mouse model, this stain can be used in subcutaneous inoculation of liver cancer tissues and tumor cells. Tumors can esaily form and grow. The amount of T and B lymphocytes in peripheral blood of mice was extremely low tested by FACS, which was comparable to or lower than that of Nude mice, and there was a significant difference compared with wild type mice. The pathological sections of HE staining of tumor tissues showed that the tumor sections of Rag2 KO mice and Nude mice were similar. This strain has the potential to replace Nude, NOD-SCID mice as a tumor-bearing mouse model.

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

Gchfr-KO

Strain Name：C57BL/6Smoc-Gchfrem1Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KO-190961

Exon 2 of Gchfr gene was deleted to generate Gchfr knockout mice.

Mice

R26-CAG-LSL-hTM6SF2*E167K-EGFP

Strain Name：C57BL/6Smoc-Gt(ROSA)26Sorem1(SA-Frt-2xpolyA-CAG-Frt-LSL-TM6SF2-IRES-GFP-WPRE-PA)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-200017

These mice harbor a SA-Frt-2xpolyA-CAG-Frt-LSL-TM6SF2-IRES-GFP-WPRE-PA cassette in the Rosa26 locus generated by homologous recombination.

Mice

Sidt2-Flox

Strain Name：B6;129S-Sidt2tm1(flox)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-CKO-00041

The Sidt2 flox allele has loxP sites flanking exon 2 of Sidt2 gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of the gene.
