Mice

Ebf1-Flox

Strain Name：B6;129S-Ebf1tm1(flox)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-CKO-00065

These mice carry loxP sites flanking exon 3 of the early B cell factor 1 gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of the gene.

Mice

NMG

Strain Name：NOD.Cg-PrkdcscidIl2rgem1Smoc
Strain State：Repository Live | Cat. NO.：NM-NSG-001

Prkdc and Il2rg genes were both knocked-out in NOD mice.  Lacking mature T, B and NK cells Low immune rejection against human cells and tissues Good tumorigenicity so that a small number of cells can form tumors. Significant improvement in the survival of transplanted human cells and tissues Suitable for the transplantation of human hematopoietic stem cells and the preparation of humanized mouse models Suitable as the carrier mice for the transplantation of heterologous cells and tissues

Mice

Ighm/Ighd-KO

Strain Name：C57BL/6Smoc-Ighmem1Ighdem1Smoc
Strain State：Repository Live | Cat. NO.：NM-KO-200610

Exon 1-6 of Ighm and exon 1-5 of Ighd gene was deleted to generate Ighm and Ighd knockout mice. Homozygous mutant mice lack mature B cells. It may be useful as a model for B cell immunodeficiency found in humans.

Mice

Cd2-2A-CreERT2

Strain Name：C57BL/6Smoc-Cd2em1(2A-CreERT2-WPRE-pA)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-18017

A 2A-CreERT2-WPRE-pA coexpression cassette is inserted befor the stop codon of mouse Cd2 gene via homologous recombination to establish a tamoxifen inducible Cd2-CreERT2 tool stain. This strain can be used to knockout target gene in T cells and B cells after tamoxifen treatment when crossed with mice which carry loxp sites flanking target gene.

Mice

NOD SCID

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

The scid mutation has been transferred onto a diabetes-susceptible Non-Obese Diabetic (NOD) background. NOD-Scid mice do not develop diabetes, lack T and B cells, and are inherently immune deficient, making them good recipients for transplantation of human hematopoietic stem cells and human solid tumors. 

Mice

BALB/c Nude

Strain Name：BALB/cAnSmoc-Foxn1nu/Smoc
Strain State：Repository Live | Cat. NO.：SM-014

This strain carries a Foxn1nu mutation on the BALB/c background which will lead to T cell deletion. At the same time, the response to thymus-dependent antigens is limited, resulting in impaired B cell function while NK cells, macrophages, and antigen-presenting cells function normally. The complement activity is normal as well. Hair dysplasia causes aberrant hair growth in which the majority of the hair cannot protrude from the surface, resulting in a naked mouse phenotype.

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

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

Cd19-IRES-EGFP-Luc

Strain Name：C57BL/6Smoc-Cd19em1(IRES-EGFP-Luci)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-200058

A IRES-EGFP-Luci expression cassette was knocked into the Cd19 gene stop codon site.
