Solvent & Solubility
DMSO : 180 mg/mL (197.55 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
Please refer to the solubility information to select the appropriate solvent. The compound is unstable in solutions, freshly prepared is recommended.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 4.5 mg/mL (4.94 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 4.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (45.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Horseradish peroxidase (HRP) is thiolated with 2-iminothiolane and conjugated to mc-MMAE to generate the HRP-MMAE reporter enzyme-drug conjugate. Briefly, a thiolation reaction mixture containing 0.2 mM HRP (8 mg/mL) and 50 mM 2-iminothiolane in 25 mM sodium borate decahydrate (Na2B4O7•10H2O) buffer (pH 9.0) is incubated for 1 hour at 37°C. Unreacted 2-iminothiolane is removed by passage through a PD-10 desalting column equilibrated in PBS (pH 7.4). Peak fractions are pooled and mc-MMAE is coupled to thiolated HRP (HRP-SH) at a molar ratio of 3:1. The final conjugation reaction mixture contained 80 μM HRP-SH (3.2 mg/mL) in sodium borate buffer [50 mM H3BO3, 50 mM NaCl (pH 8.0); 80% v/v] and 240 μM mc-MMAE in ice-cold CH3CN (20% v/v). After 30 minutes on ice, the reaction is terminated with a 20-fold molar excess of free cysteine (4.8 mM) before PD-10 chromatography. Peak fractions containing HRP-MMAE (exchanged into PBS) are pooled and evaluated for extent of modification using the thiol-reactive dye, Alexa Fluor 594 C5 maleimide[1].
