Alb-Cre+/MYC+ mice are generated by crossing H11-CAG-LSL-hMYC-IRES-EGFP mice (Catalog Number: C001338), which conditionally express the human c-Myc oncogene, with Alb-Cre mice that express Cre recombinase specifically in hepatocytes under the control of the Alb promoter. The Cre-mediated recombination results in the deletion of the transcriptional stop sequence (Loxp-Stop-Loxp, LSL) in H11-CAG-LSL-hMYC-IRES-EGFP mice, leading to overexpression of the MYC oncogene in the liver and subsequent carcinogenesis. This model, therefore, spontaneously develops liver cancer with an early onset.

B6-H11-hCLEC4C mice are humanized models generated by gene editing technology, in which the human CLEC4C genomic DNA was inserted at the H11 safe harbor. This modification does not affect the expression of the mouse homologous gene Clec4b1. This model can be used to study the pathological mechanisms and therapeutic methods of autoimmune disorders and hematological malignancies, as well as the screening and development of CLEC4C-targeted drugs, and preclinical efficacy and safety evaluations.

The B6-RCL-hLPA/Alb-cre/TG (APOB) mice express human LP(a) and ApoB, two risk factors for cardiovascular disease. It can be used in the study of hyperlipidemia, stroke, coronary heart disease, familial hypercholesterolemia (FH), and other atherosclerotic cardiovascular diseases (ASCVD). Internal data (not shown) indicates that, compared to the Cyagen strain B6-LPA (CKI) /Alb-Cre & Tg (APOB) mice (Catalog No. C001494), this model exhibits a more stable expression of human LPA protein at different ages. Please choose the model based on the experimental need for continuous stability of human LPA protein expression.

The B6-h4-1BB (TNFRSF9) mouse is a humanized model. The sequence encoding the endogenous extracellular domain of the mouse Tnfrsf9 is replaced in situ with the sequence encoding the human TNFRSF9 extracellular domain. This model can be used for studies on cancer immunology and autoimmune diseases, as well as for the development, screening, and evaluation of 4-1BB agonists in preclinical research.

B6-h4-1BB/hPDL1 mice are TNFRSF9 and CD274 double humanized mouse models obtained by mating TNFRSF9 humanized mouse models (Catalog No. C001604) with CD274 humanized mouse models (Catalog No. C001235). They express human TNFRSF9 and CD274 genomic sequences under the control of mouse promoters. This model is a valuable tool for studying cancer immunotherapy. In addition, this model also provides a powerful preclinical research platform for evaluating the efficacy and mechanism of therapeutic drugs targeting TNFRSF9 and CD274.

B6-hALB/hTFRC mice are a dual gene humanized model of Alb and Tfrc, obtained by crossing B6-hALB (HSA) mice (Catalog number: C001492) with B6-hTFRC (CDS) mice (Catalog number: C001584). This model can be used for the development of ALB/TFRC-targeted therapeutic drugs, as well as for the research on drug development using human serum albumin (HSA) as a carrier or drug delivery across the blood-brain barrier (BBB), and for in vivo pharmacodynamic and pharmacokinetic studies.

The B6-hALK7 (hACVR1C) mouse is a humanized model constructed using gene editing technology, where the region from aa.27 in exon 2 to partial intron 2 of mouse Acvr1c was replaced with "ACVR1C chimeric CDS-WPRE-BGH pA" cassette. The murine signal peptide (aa.1~25) of Acvr1c was preserved. This model can be used for studying the pathological mechanisms and therapeutic approaches of metabolic disorders such as obesity and type 2 diabetes, and certain cancers like retinoblastoma, and for the development of ACVR1C-targeted drugs.

B6-hANG2 (ANGPT2) mouse model was generated using gene editing technology to replace the entire sequence of the mouse Angpt2 gene with the human ANGPT2 gene sequence, achieving stable expression of human ANGPT2 protein. This model is suitable for studying tumorigenesis, vascular hyperproliferative diseases (e.g., diabetic retinopathy, age-related macular degeneration), autoimmune disorders, and preclinical evaluation of human ANGPT2-targeted therapeutics.

The B6-hB2M&HLA-A2.1/mB2m KO mice are a humanized model obtained by mating H11-hB2M&HLA-A2.1 mice (Catalog Number: I001138) with B2m gene knockout mouse model (Catalog Number: S-KO-19919). While knocking out the mouse B2m gene, the chimeric H2-K1 HLA-A2.1 gene is integrated into the H11 safe harbor locus, which may be able to recapitulate the immune response of the human HLA-A*0201 (MHCI) subtype. This model can play an important role in studying the determinants of HLA-A2.1-restricted cytotoxic T lymphocytes (CTLs) and the development of potential viral vaccines and helps research the human immune response to a variety of antigens.

The B6-hB7-H3 (hCD276) mouse is a humanized model constructed by replacing the sequence of the mouse Cd276 endogenous extracellular domain (aa.29~248) in situ with the corresponding extracellular domain from the human CD276. The murine signal peptide (aa.1~28) and aa.249~316 were preserved. The B6-hB7-H3 (hCD276) mice can be used for the study of the pathogenesis of various cancers such as breast cancer, glioblastoma, and non-small cell lung cancer, as well as for CD276-targeted drug development.
