Arthritis Models

Dexamethasone (Hexadecadrol) is a glucocorticoid receptor agonist, apoptosis inducer, and common disease inducer in experimental animals, constructing models of muscle atrophy, hypertension, and depression. Dexamethasone can inhibit the production of inflammatory miRNA-155 exosomes in macrophages and significantly reduce the expression of inflammatory factors in neutrophils and monocytes. Dexamethasone also has potential for use in COVID-19 research.

Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O55:B5 possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. Lipopolysaccharides, from E. coli O55:B5 can be widely used to induce cellular inflammation and establish animal models related to inflammation.
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.

Complete Freund's adjuvant (CFA) is an immunoadjuvant emulsified with antigen by its discoverer Jules T. Freund to enhance an animal's immune response to an antigen. Complete Freund's adjuvant (CFA) is also an inducer of the Th1 immune response and a ligand of TLRs. Complete Freund's adjuvant (CFA) contains heat-killed inactive tuberculosis bacilli and consists of a paraffin oil-in-water emulsion. Complete Freund's adjuvant (CFA) stimulates a strong and durable immune response and can be used to induce persistent inflammatory pain models in mice, experimental autoimmune myocarditis (EAM) models, and more. Incomplete Freund's adjuvant (IFA) (HY-153808A) is another type of Freund's Adjuvant that stimulates a weaker immune response.

Incomplete Freund's adjuvant (IFA) (Montanide ISA-51) is an immunoadjuvant emulsified with antigen by its discoverer Jules T. Freund. Incomplete Freund's adjuvant (IFA) does not contain inactivated tuberculosis bacilli and consists of petroleum jelly containing lanolin. Incomplete Freund's adjuvant (IFA) induces high antibody titers and long-lasting effector T cell responses with no long-term effects on collagen disease, tumors, or death. Complete Freund's adjuvant (CFA) (HY-153808) is another type of Freund's Adjuvant that stimulates a stronger immune response.

Collagen, Type II, from bovine snout membrane is a type II collagen that can be used for cell culture. This product is enzymatically hydrolyzed collagen peptides.

Mannan is an orally active polysaccharide compound that binds to the mannose receptor (MR). Mannan promotes bacterial uptake and endosomal degradation by binding to MR, thereby enhancing the production of IL-12 in immune cells. Mannan enhances ROS production. Mannan modulates immunity, inhibits Aflatoxin B₁ (HY-N6615)-induced toxicity, and reduces lipid.

Complete Freund's adjuvant (CFA, 1 mg/ml) is an immunoadjuvant emulsified with antigen that can enhance an animal's immune response to an antigen. Complete Freund's adjuvant (CFA, 1 mg/ml) is also an inducer of the Th1 immune response and a ligand of TLRs. Complete Freund's adjuvant (CFA, 1 mg/ml) contains heat-killed inactive tuberculosis bacilli and consists of a paraffin oil-in-water emulsion. Complete Freund's adjuvant (CFA, 1 mg/ml) stimulates a strong and durable immune response and can be used to induce rheumatoid arthritis in rats, and more.

Ovalbumin, low endotoxin are the major proteins in egg white. Ovalbumin, low endotoxin act as an allergen and inducer, and can be applied to mouse models of allergic diseases. Ovalbumin, low endotoxin can induce allergic rhinitis in mice via sensitization and nasal challenge. Ovalbumin, low endotoxin can be used to establish asthma models.

G6PI 325-339 (human) is an efficient inducer of arthritis in B10.Q mice. G6PI 325-339 (human) primes Th1 and Th17 cells cross-reacted with the murine G6PI protein. G6PI 325-339 (human) induces arthritis model operating through a T and B cell-dependent pathway but without antibody effector mechanisms.

CP-20961 is an interferon inducer. CP-20961 is a potent synthetic non-immunogenic adjuvant that induces arthritis.

G6PI 325-339 (human) hydrochloride is an efficient inducer of arthritis in B10.Q mice. G6PI 325-339 (human) hydrochloride primes Th1 and Th17 cells cross-reacted with the murine G6PI protein. G6PI 325-339 (human) hydrochloride induces arthritis model operating through a T and B cell-dependent pathway but without antibody effector mechanisms.
