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

Crhr1/N-EGFP-Flox

Strain Name：C57BL/6Smoc-Crhr1em1(N-EGFP, flox)Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-CKO-2100082

These mice carry loxP sites flanking exon 2 of Crhr1 gene. The EGFP element is inserted into exon 2 of Crhr1 gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of Crhr1 gene. Construction strategy references Glutamatergic and dopaminergic neurons mediate anxiogenic and anxiolytic effects of CRHR1.

Mice

Lepr-g.G109052T

Strain Name：B6.129S-Leprtm1Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-00001

A point mutation was introduced to exon 19 (c.109052 G>T) via a recombineering strategy. Homozygous mutants are hyperphagic, low-activity, poorly cold-adapted, sterile and have enhanced fat conversion.

Mice

Icosl-KO(3)

Strain Name：C57BL/6Smoc-Icoslem1Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KO-210308

Icosl-KO(3) mice(Stock No.NM-KO-210308) carry a knockout allele derived from the targeted deletion of exon 2-3. While Icosl-KO mice(Stock No.NM-KO-190721) and Icosl-KO(2) mice(Stock No.NM-KO-200716) carrying the exon 2 deletion.

Mice

F9-KO

Strain Name：C57BL/6Smoc-F9em1Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KO-18046

The F9 gene is located on the X chromosome. In this F9 knockout mouse model, gRNAs were designed targeting Exon8 of F9 gene via CRISPR gene editing technology. Loss of F9 caused coagulopathy in mice. Mice that are homozygous for F9 knockout are viable, fertile and normal in size. Normal fighting in the cage may cause bleeding or even death due to massive internal hemorrhaging. After the tail cutting, wounds must be cauterized to prevent homozygous knockout mice from blood loss and death. This strain is a powerful model for studying coagulopathy, gene therapy methods and function of factor IX mutations. F9-KO mice (Stock No.NM-KO-18046）carry a knockout allele derived from the targeted deletion of exon 8. While F9-KO(2) mice (Stock No.NM-KO-200607) carrying the exon 1-8 deletion.

Mice

Ace2-2A-CreERT2

Strain Name：C57BL/6Smoc-Ace2em2(2A-CreERT2-WPRE-polyA)Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KI-200187

A 2A-CreERT2-WPRE-polyA expression cassette was knocked into the Ace2 gene stop codon site. Ace2 encodes angiotensin I converting enzyme 2. When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in cells expressing Cre. This strain is useful for studying lung injury and kidney disease caused by SARS coronavirus infection.

Mice

R26-pVillin1-hCYP3A4-IRES-tdTomato(FVB)

Strain Name：FVB-Gt(ROSA)26Sorem1(Gut-CYP3A4-IRES-tdTomato)Smoc
Strain State：Embryo cryopreservation | Cat. NO.：NM-KI-18033

Intestinal expression of the CYP3A enzyme in the human body can cause significant intestinal metabolism of the compound, resulting in impaired drug absorption. This knock-in model was generated by inserting the human CYP3A4 cDNA driven by the Villin1 promoter together with the IRES-tdTomato reporter gene into mosue Rosa26 site, which can be crossed with the Cyp3a13 gene knockout and other Cyp3a family genes knockout mice to obtain intestinal-expressed CYP3A4 humanized mouse model in order to determine the contribution of intestinal metabolism to the absorption and distribution of test article.

Mice

Vip-IRES-Cre

Strain Name：C57BL/6Smoc-Vipem1(IRES-iCre-SV40-pA)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-200100

A IRES-iCre expression cassette was knocked into the Vip gene stop codon site. Vip encodes vasoactive intestinal polypeptide. When crossed with a strain carrying a gene flanked by sites, the flanked gene will be removed in cells expressing. This strain is useful for studying bronchiectasis, immunomodulatory and anti-inflammatory.

Mice

Slco1c1-2A-CreERT2

Strain Name：C57BL/6Smoc-Slco1c1em1(2A-CreERT2)Smoc
Strain State：Repository Live | Cat. NO.：NM-KI-200262

2A-CreERT2 expression cassette was knocked into the Slco1c1 gene stop codon site. Slco1c1 encodes a member of the organic anion transporter family. The encoded protein is a transmembrane receptor that mediates the sodium-independent uptake of thyroid hormones in brain tissues. This protein has particularly high affinity for the thyroid hormones thyroxine, tri-iodothyronine and reverse tri-iodothyronine. When Slco1c1-2A-CreERT2 mice are bred with mice containing loxP-flanked sequence, tamoxifen-inducible, Cre-mediated recombination will result in deletion of the floxed sequences in SLCO1C1 positive cells.

Mice

Foxn1-IRES-Cre

Strain Name：C57BL/6Smoc-Foxn1em1(IRES-iCre)Smoc
Strain State：Sperm cryopreservation | Cat. NO.：NM-KI-200106

A IRES-iCre expression cassette was knocked into the Foxn1 gene stop codon site. The protein encoded by Foxn1 (forkhead box N1) gene is part of the forkhead family or transcription factors that are important in developmental processes, immune system regulation, metabolism, cancer and aging. When crossed with a strain carrying a gene flanked by sites, the flanked gene will be removed in thymic epithelial cell and keratinocytes.
