In human PBMC, ODN 2088 (0.01, 0.1, 1, 10 μM; 48 hours) does not cause cytotoxicity [1]. ODN 2088 (0.01, 0.1, 1, 10 μM; 24 h) blocks human PBMCs activated by TLR7-ligand RNA-ORN 22075 (5 μM) and CpG-ODN 2216 (3 μM) from releasing IFN-α[1]. Iripimod (5 μg/ml)-stimulated IL-6 release in human PBMC is inhibited by ODN 2088 (0.01, 0.1, 1, 10 μM; 48 h), although CpG-ODN 2006 (100 nM)-stimulated IL-6 release is weakly inhibited[1]. When B cells are activated with CpG-DNA 2006 (100 nM), ODN 2088 (0.1, 1, 10 μM; 24 h) hardly decreases IL-6 release; however, when humans are stimulated with imiquimod (5 μg/ml), IL-6 release from B cells is inhibited[1]. When CpG-ODN 2006 or imiquimod are not present, ODN 2088 (1, 10 μM; 48 hours) boosts the expression of CD86 and HLA-DR in CD20+ B cells [1]. ODN 2088 binds to the C-terminal region of TLR9 competitively, which may hinder CpG-ODN-induced TLR9-induced signaling [1]. When BMDM were treated with CpG-ODN 1826 (100 nM), ODN 2088 (0.001, 0.01, 0.1, 1, 10 μM; 24 h) demonstrated a dose-dependent suppression of TNF-α secretion, with a weekly inhibition. imiquimod, the agonist [3]. B cell proliferation is stimulated by ODN 2088 (10 μM) [3].

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
