Vsir-KO(2)

Strain Name：C57BL/6Smoc-Vsirem5Smoc
Strain State：Developing | Cat. NO.：NM-KO-200649

Vsir-KO(2) mice(Stock No.NM-KO-200649）carry a knockout allele derived from the targeted deletion of exon 2. While Vsir-KO mice (Stock No.NM-KO-18047) carrying the exon 2-3 deletion.

Mice

Rag2-KO

Strain Name：C57BL/6Smoc-Rag2em2Smoc
Strain State：Repository Live | Cat. NO.：NM-KO-190429

Partial exon 3 of Rag2 gene was deleted to generate Rag2 knockout mice. Deletion of this region will cause frameshift and result in loss of function of mouse Rag2 gene.

Mice

hIL6

Strain Name：C57BL/6Smoc-Il6tm1(hIL6)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-HU-18017

This IL6 humanized mouse model was established by replacing the mouse Il6 gene coding exon1-5 and introns with the human IL6 corresponding sequence by homologous recombination via ES cell targeting.

Mice

Gsdmd-KO

Strain Name：C57BL/6Smoc-Gsdmdem1Smoc
Strain State：Repository Live | Cat. NO.：NM-KO-191212

This Gsdmd knockout mouse model was generated by deleting the exon 2-3 region of the Gsdmd.

Mice

H11-CAG-LSL-Myc

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

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

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

SCID

Strain Name：SCID/NifdcSmoc
Strain State：Repository Live | Cat. NO.：SM-015

SCID mice, also known as Severe Combined Immune Deficient mice, were first discovered in 1983 by Bosma M.J. from the C.B-17/Icr inbred strain of mice. This condition is caused by a mutation in a single recessive gene located on chromosome 16, also referred to as the SCID gene. SCID mice are a congenic strain of C.B-17/lcrJ, with white fur. This strain exhibits severe combined immune deficiency, characterized by the absence of functional B cells and T lymphocytes. Most homozygotes lack detectable levels of IgM, IgG1, IgG2a, IgG2b, IgG3, or IgA. Additionally, the thymus, lymph nodes, and splenic follicles of these mice are virtually devoid of lymphocytes. However, SCID mice possess normal natural killer (NK) cells, macrophages, and granulocytes. SCID mice are commonly used for the transplantation of allogeneic or xenogeneic tissues and are ideal models for cell transplantation experiments.

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.

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.

Tagln-Cre

Strain Name：C57BL/6Smoc-Taglnem1(Cre-WPRE-polyA)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-200144

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.
