YZ-35 is a STAT3 inhibitor, with a Ki value of 0.38 μM. YZ-35 binds directly to STAT3 with high affinity, exhibiting a dissociation constant (Kd) of 190 nM. YZ-35 directly attenuates the dual phosphorylation of STAT3 (Tyr705 and Ser727). YZ-35 suppresses colony formation, cellular migration, and induces apoptosis in breast cancer cell lines (BCSC). YZ-35 selectively suppresses BCSC self-renewal. YZ-35 inhibits tumor growth in the BCSC xenograft models. YZ-35 can be used for the study of breast cancer.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
