Irf4-KO

Strain Name：C57BL/6Smoc-Irf4em1Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KO-190100

This Irf4 knockout mouse model was generated by knocking out the exon 3 region of the Irf4.

Mice

Csf1-KO

Strain Name：C57BL/6Smoc-Csf1em1Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KO-190063

This Csf1 knockout mouse model was generated by knocking out the exon 4-5 region of the Csf1 .

Mice

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
Validation Data：Presence  |  Publications：2piece

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

Mt1-Flox/Mt2-Flox

Strain Name：C57BL/6Smoc-Mt1 em1（flox）Mt2 em1（flox）Smoc
Strain State：Repository Live | Cat. NO.：NM-CKO-252576

The MT1-FLOX model was constructed based on Mt2-Flox (NM-CKO-226357) by inserting loxP sites on both sides of exon 2-3 of the Mt1 gene respectively. This flox mouse can be mated with tissue-specific Cre tool mice to obtain mouse models with the Mt1 gene knocked out in specific cell types or tissues.

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
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

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.
