Cat.No.E4759

MS41 is a highly potent and selective PROTAC degrader of eleven-nineteen leukemia (ENL) that recruits the von Hippel–Lindau (VHL) E3 ubiquitin ligase, with DC50 values of 3.50 nM (MV4;11), 2.84 nM (SEMK2), 3.03 nM (Jurkat), and 26.58 nM (KASUMI1). It suppresses oncogenic gene expression, inhibits leukemia cell proliferation, and reduces MLL-r leukemia progression in a xenograft mouse model.

In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	1.250mg/ml (1.21mM)	Taking the 1 mL working solution as an example, add 50 μL of 25 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
