Biochemical and Physiological Mechanisms

XAV939 is a potent, small molecule inhibitor of tankyrase 1 (TNKS) (IC50 = 11 nM) and tankyrase 2 (IC50 = 4 nM). By inhibiting TNKS activity, XAV939 increases the protein levels of the axin-GSK3β complex and promotes the degradation of β-catenin in SW480

Note

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.
