EG31 is an EGFR inhibitor. EG31 effectively inhibits the proliferation of triple-negative breast cancer (TNBC) cells (GI50 values of MDA-MB-231 and Hs578T cells are 498.90 nM and 740.73 nM, respectively) and induces apoptosis by inhibiting the EGFR signaling pathway. EG31 still maintains antiproliferative activity against 5-fluorouracil (5-FU)-resistant TNBC cells (GI50: 519.5 nM). EG31 can be used to study TNBC resistance.

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.
