Broad model portfolio – Spontaneous (MRL/lpr), chemical (pristane), TLR-driven (imiquimod), antigen-driven (ALD-DNA, apoptotic cells), and humanized models.
Multiple strains – MRL/lpr, C57BL/6, BALB/c, and humanized mice available.
Comprehensive endpoints – Body weight, lymphadenopathy/spleen/kidney indices, anti-dsDNA, proteinuria, serum CREA/LDH/AST, renal histopathology (HE, IgG deposition), flow cytometry (B cells, plasma cells, T cells).
Translational value – Ideal for testing immunosuppressants, biologics (anti-CD20, anti-IFNAR), TLR inhibitors, and B cell‑targeted therapies.
IND-ready data packages – Studies can be conducted in accordance with GLP principles.

A1: We provide a full range of SLE models, including MRL/lpr spontaneous model, Pristane, TLR-7 agonist, ALD-DNA and apoptotic cell induced models with C57BL/6 and BALB/c mice. We also offer TLR-7 agonist induced humanized mouse model.
A2: The spontaneous MRL/lpr mice naturally develop systemic autoimmunity. Induced models trigger abnormal immune activation, excessive autoantibody production and immune complex deposition, which highly recapitulate the pathological features of human SLE.
A3: We monitor body weight, organ indexes and lymphadenopathy. We test anti-dsDNA autoantibodies and proteinuria, analyze immune cell subsets, and perform HE staining for kidney and heart pathological evaluation.
A4: The MRL/lpr model is observed from Week 10 to Week 22. Pristane model lasts 26 weeks, TLR-7 agonist model runs 12 weeks, and ALD-DNA induced model takes 12 weeks in total.
