Auristatin |
Antibody-drug conjugates (ADC) comprise targeting antibodies armed with potent small-molecule payloads. ADCs are generated to target different receptors on the anaplastic large cell lymphoma line L-82, but delivered the same cytotoxic payload (monomethyl auristatin E, MMAE), and the intracellular concentration of released MMAE correlated with in vitro ADC-mediated cytotoxicity independent of target expression or drug:antibody ratios. LC-MS is used to measure the concentration of MMAE in a parallel cohort of L-82 tumors with an identical treatment regimen. Although tumor volume is not different among treatment groups 3 days after dose, the intratumoral MMAE measurement reveals two patterns. First, intratumoral MMAE concentration increases proportionally to the ADC dose, which correspondes to stronger antitumor activity. Second, the intratumoral MMAE concentration obtained from treatment with both cOKT9-vcMMAE and cAC10-vcMMAE is similar at each dose, consistent with the observation that tumor responded similarly to these two ADCs[1].

Solvant et solubilité
DMSO : 100 mg/mL (137.74 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. The compound is unstable in solutions, freshly prepared is recommended.
Please refer to the solubility information to select the appropriate solvent. The compound is unstable in solutions, freshly prepared is recommended.
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.44 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.44 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

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.
Protocole
Cell pellets are collected 24 hours after ADC treatment. Cell count, diameter, and circularity are determined on Vi-Cell Counter. MMAE extraction and quantification method is performed. Briefly, tumors or cell pellets are homogenized with methanol and acetonitrile containing internal standard (d8-MMAE for MMAE detection and 13C-MMAF for MMAF detection). The homogenates are centrifuged at 10,000 rpm to precipitate protein and protein-bound payloads. The supernatant is then subjected to solid phase extraction, and signals of MMAE and MMAF are detected by LC-MS[1].
