Guselkumab

Catalog No. T38362Cas No. 1350289-85-8
Alias CNTO 1959

Guselkumab (CNTO 1959) is a recombinant human IgG1 monoclonal antibody targeting the IL-23p19 subunit. Guselkumab binds to human cynomolgus monkey IL-23 with Kd values of 3.3 and 1.9 pmol/L, respectively. Guselkumab can inhibit the production of cytokines downstream of IL-23 signaling pathway, and can be used in the study of psoriatic arthritis.

Description
Guselkumab (CNTO 1959) is a recombinant human IgG1 monoclonal antibody targeting the IL-23p19 subunit. Guselkumab binds to human cynomolgus monkey IL-23 with Kd values of 3.3 and 1.9 pmol/L, respectively. Guselkumab can inhibit the production of cytokines downstream of IL-23 signaling pathway, and can be used in the study of psoriatic arthritis.
Targets&IC50
IL-23 (monkey):1.9 pM, STAT3 phosphorylation:102.1100±2.0053 nM, IL-23:0.06 pM(kd), IL-23:0.06 nM (IC50), IL-23 (human):3.3 pM
In vitro
Guselkumab effectively suppresses the production of Th17 cytokines, including IL17A, IL-17F, and IL-22, in mouse splenocytes stimulated with IL-23 concentrations of 0.5 or 1 ng/mL, demonstrating IC50 values between 0.016-0.080 nM. It also inhibits the IL-23 (10 or 100 ng/mL) driven production of IL-10 in human NKL cells. However, guselkumab does not impact the IL-12 (0.1 ng/mL) mediated production of interferon γ (IFNγ) in NK92MI cells. In combination with IBI112, guselkumab can prevent IL-23-induced STAT3 phosphorylation, showing an IC50 of 102.1100±2.0053 nM. Additionally, guselkumab blocks the induction of mIL-17 production by hIL-23 in a dose-dependent manner with an IC50 of 4.9743 ±1.2847 nM and inhibits IL-17F production in cynomolgus monkeys with an IC50 of 16.7950 nM.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
