Biotin-epoxomicin
Based on 1 Customer Validation
Biotin-epoxomicin is a Proteasome subunit binder. Biotin-epoxomicin serves as an affinity reagent for identifying proteasomal catalytic subunits, and facilitates affinity purification of active proteasomal subunits for LC-MS identification. Biotin-epoxomicin can be used to study solid tumors derived from B16 melanoma.

Solvent & Solubility
In Vitro:
DMSO : 50 mg/mL (68.97 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. 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 (sealed storage, away from moisture). 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.
