EMI66 (EMI-66) is a small molecule that attenuates RTK expression and signalling and alters the electrophoretic mobility of Coatomer Protein Complex Beta 2 (COPB2, binding Kd=1.51 uM) in lung cancer cells.EMI66 affects the subcellular localization of EGFR and COPB2, altering the endoplasmic reticulum (ER) stress response pathway, resulting in growth inhibition of mutant EGFR lung cancer cells and organoids.EMI66 inhibited total EGFR and MET levels, activation, and downstream signalling at lower concentrations than EMI1, also binds to recombinant COPB2 protein with an increased affinity compared to EMI1.EMI66 exerts an anti-proliferative effect (EC50=3-5 uM) on primary lung cancer organoid models, including XDO-137 (EGFR ex19del), PDXO-4000 (EGFR ex19del) and XDO-344 (wild-type EGFR).

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.
