NX-2127 is a potent, selective, and orally bioavailable BTK degrader with Kd of 18 nM (for WT BTK), 45 nM (BTK C481S), 18 nM (BTK T474I), 44 nM (BTK M437R), 97 nM (BTK V416L), and 88 nM (BTK L528W), respectively. NX-2127 efficiently engages the intracellular ubiquitin-proteasome system to simultaneously bind both BTK and the CRBN E3 ubiquitin ligase complex, inducing polyubiquitination and proteasome-dependent degradation of BTK, IKZF1, and IKZF3.

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.
