EM12-FS
Based on 1 Customer Validation
EM12‑FS is a selective covalent molecular glue degrader of NTAQ1 that binds to CRBN with an IC50 of 256 nM. EM12‑FS covalently modifies the His353 residue of CRBN via chemical modification, reshapes the surface conformation of CRBN protein, selectively recruits NTAQ1 to form a ternary complex, and mediates the degradation of NTAQ1 protein in a CRL4CRBN E3 ubiquitin-proteasome pathway-dependent manner. EM12‑FS can be used in cancer-related research.

In Vitro
EM12-FS binds to cereblon in HEK293T cells with an IC50 of 256 nM; it covalently and specifically labels the His353 residue of recombinant CRBN in a cell-free biochemical system[1][2].
EM12-FS is a molecular glue degrader that selectively degrades the NTAQ1 protein in human leukemia cell lines MOLT4 and THP1[1][2].
EM12-FS exhibits high metabolic stability, with a half-life of 196 min in human plasma, >145 min in human liver microsomes, and >217 min in human hepatocytes[2].
EM12-FS (1-5 μM) mediates the degradation of endogenous and FLAG-tagged NTAQ1 in MOLT4 cells in a neddylation-dependent manner[2].
EM12-FS induces time-dependent dimerization of CRBN and NTAQ1 in a cell-free TR-FRET assay, and the degree of dimerization correlates with the level of covalent labeling of CRBN at the His353 site[2].

Solvent & Solubility
In Vitro:
DMSO : 25 mg/mL (73.04 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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.30 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.
