LO-4-25
Based on 1 Customer Validation
LO-4-25 is a CUL4DCAF16 based covalent PROTAC-like degrader. LO-4-25 induces degradation of the androgen receptor (AR) and androgen receptor truncation variant AR-V7. LO-4-25 covalently targets cysteine residues on CUL4DCAF16 to mediate degradation of neo-substrates. LO-4-25 triggers proteasome-dependent degradation of target proteins via CUL4DCAF16-mediated ubiquitination. LO-4-25 can be used for the research of androgen-independent prostate cancer.

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (153.09 mM; ultrasonic and warming and heat to 60°C; 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. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
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.
