NOD SCID

Strain Name：NOD.Cg-Prkdcscid/NifdcSmoc
Strain State：Repository Live | Cat. NO.：SM-019
Validation Data：Presence

The strain was developed on background of non-obese diabetic (NOD) mouse with spontaneous scid mutation. NOD SCID mouse, insusceptible to diabetes, possesses reduced activity of T cells and B cells, and defect in innate immunity.NOD SCID mouse is compatible with a wider range of engraftment of cell lines in comparison with nude mouse; And it is broadly applied to construction of PDX models. However, due to a short life span(8-9 months) caused by lethal thymic lymphomas, it is unsuitable for long-term in vivo assays.

Strain State：Embryo cryopreservation | Cat. NO.：NM-TG-00001
Validation Data：Presence  |  Publications：1piece

The transgenic mice model could be used to study transcriptional regulation of the IL-1βgene expression in the inflammatory process and evaluation the effect of anti-inflammatory drug in vivo.

hTLR8/Lyz2-DTREGFP

Strain Name：C57BL/6Smoc-Lyz2tm3(IRES-DTREGFP)Tlr8tm2(TLR8)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-HU-200259

NM-KI-190041 was crossed with NM-HU-190044 to generate hTLR8/Lyz2-IRES-DTREGFP mice.

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
Validation Data：Presence

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

Tagln-Cre

Strain Name：C57BL/6Smoc-Taglnem1(Cre-WPRE-polyA)Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KI-200144
Validation Data：Presence

A Cre-WPRE-polyA expression cassette was knocked into the Tagln gene start codon site. This gene encodes a smooth muscle cell-specific cytoskeletal protein. When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in vascular smooth muscle cells. In mouse models of atherosclerosis, the gene product may be involved in plaque cell and atherosclerotic lesion formation during atherogenesis.

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
Validation Data：Presence  |  Publications：5piece

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

H11-CAG-LSL-Myc

Strain Name：C57BL/6Smoc-Igs2em1(CAG-LSL-Myc)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-00039
Validation Data：Presence  |  Publications：2piece

The c-Myc gene (also known as Myc) is abnormally expressed in many tumors and plays a critical role in the regulation of cell proliferation, growth and metabolism, gene instability, stimulation of angiogenesis, malignant transformation, cell differentiation and apoptosis. These mice harbor a loxP-flanked STOP cassette preventing transcription of a CAG promoter-driven Myc oncogene. The targeted mutation was inserted into the Hipp11(H11) locus by homologous recombination. Myc is expressed when bred to mice that express Cre recombinase.

Mice

KPC

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

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

Atp4b-IRES-CreERT2(2)

Strain Name：C57BL/6Smoc-Atp4bem2(IRES-CreERT2)Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KI-210119
Validation Data：Presence

An IRES-CreERT2 expression cassette was knocked into the Atp4b gene stop codon site. Besides,An IRES-CreERT2-WPRE-pA expression cassette were knock into the Atp4b gene start codon site to generate Atp4b-IRES-CreERT2(Stock No. NM-KI-210118) mice. ATP4B could serve as a tumor suppressor in the tumorigenesis and progression. This strain is useful in studying the function of gastric parietal cells in gastric epithelial homeostasis. When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in cre-expressing cells after tamoxifen treatment.
