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.

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-hBAFF (TNFSF13B) mouse is a humanized model generated using gene editing technology, in which the protein-coding sequence (CDS) encoding the extracellular domain of the human TNFSF13B protein is integrated into a specific site within the mouse Tnfsf13b gene, while retaining the endogenous gene sequence encoding the mouse cytoplasmic and transmembrane domains (aa.1-68). Homozygous B6-hBAFF (TNFSF13B) mice are viable and fertile. This model can be used for studying the pathological mechanisms and therapeutic approaches of autoimmune diseases and specific B cell malignancies and for the development of BAFF-targeted drugs.

The B6-hBAFFR (hTNFRSF13C) mouse is a humanized model constructed by replacing the sequence of the mouse Tnfrsf13c endogenous extracellular domain (aa.1~71) in situ with the corresponding extracellular domain (aa.1~78) from the human TNFRSF13C. The B6-hBAFFR (hTNFRSF13C) mice can be used for the study of the pathogenesis of immune-mediated disorders such as common variable immunodeficiency (CVID), systemic lupus erythematosus (SLE), and Sjögren's syndrome, and certain B cell malignancies, as well as for TNFRSF13C-targeted drug development.

The B6-hC3 mouse is a mouse C3 humanized model created by replacing the mouse C3 gene with the human C3 gene using gene-editing technology. The humanized regions include the 5’UTR and 3’UTR. Under natural breeding conditions, homozygous B6-hC3 mice exhibit mortality around 10 weeks of age, and it has been observed that heterozygous mice also experience mortality.

The B6-hC3/hTFRC (CDS) mouse model is a humanized model obtained by breeding B6-hC3 mice (Catalog No.: I001135) with B6-hTFRC (CDS) mice (Catalog No.: C001584). This model can be used for research on complement-mediated diseases, iron metabolism disorders, neurodegenerative diseases, and tumor development, aiding in studying C3/TFRC-targeted drugs.

The B6-hC5 mouse model is a humanized model of the Hc gene, with the mouse Hc gene homologous to the human C5 gene. Using gene-editing technology, the mouse Hc gene was replaced with the human C5 gene while retaining the mouse signal peptide; the humanized region also includes the 3’ UTR. In addition, based on the independently developed TurboKnockout fusion BAC recombination technology, Cyagen can also generate mutation models based on this strain and provide customized services.

The B6-hCFB mouse is a humanized model constructed by replacing the sequence of the mouse Cfb gene in situ with the corresponding sequence from the human CFB gene. The homozygous B6-hCFB mice are viable and fertile and can be used for studies on age-related macular degeneration (AMD), atypical hemolytic uremic syndrome (aHUS), and systemic lupus erythematosus (SLE), and pathogenesis of immune-related diseases, as well as for CFB-targeted drug development.

This strain is a mouse Gdf15 gene humanized model expressing human GDF15 protein obtained by replacing the sequence encoding the endogenous structural domain in the mouse Gdf15 gene with the sequence encoding the structural domain in the human GDF15 gene. B6-hGDF15 mice can be used for research on metabolic diseases, cardiovascular diseases, tumor occurrence and development, etc., to assist in the preclinical evaluation of GDF15-targeted drugs.

B6-hIGF1R mice are humanized models generated using gene editing technology by integrating the protein-coding sequence (CDS) encoding the extracellular domain of human IGF1R protein and the intracellular domain of mouse IGF1R protein into the mouse Igf1r gene locus, while retaining the endogenous gene sequence encoding the signal peptide of mouse IGF1R protein (aa.1-30). Homozygous B6-hIGF1R mice are viable and fertile, and can be used for studying the pathological mechanisms and treatments of growth retardation, diabetes, and cancer, as well as for screening, developing, and preclinical efficacy and safety evaluation of IGF1R-targeted drugs.
