Product nameXAV939, Tankyrase inhibitor
DescriptionPotent tankyrase inhibitor. Inhibitor of Wnt/β-catenin signaling.
Biological descriptionPotent tankyrase (TNKS) inhibitor. Inhibitor of Wnt/β-catenin signaling. (IC50 values are 11 and 4 nM for TNKS1 and 2, respectively). Inhibits TNKS PARP activity. Selectivity over other PARP enzymes and CRE, NK-κB and TGF-β.
Storage instructionsStore at Room Temperature. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 25 mM
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.

Our Abpromise guarantee covers the use of ab120897 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Functional Studies||Use at an assay dependent concentration.|
ab16051 staining ß-catenin in SW480 cells treated with XAV939 (ab120897), by ICC/IF. Increase of ß-catenin cytoplasmic expression and decrease in nuclear expression correlates with increased concentration of XAV939, as described in literature.
The cells were incubated at 37°C for 6 hours in media containing different concentrations of ab120897 (XAV939) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab16051 (1 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
