Mechanism of Action

Information	XAV-939 is a specific tankyrase inhibitor. It affects the Wnt/β-catenin signaling pathway by stabilizing Axin and promoting β-catenin degradation, effectively inhibiting tumor cell proliferation, migration, and chemoresistance, while modulating stem cell differentiation.

Frequently Asked Questions

Question 1:
I want to inject it (Cat # S1180) into mice through I.P. and just wonder what kind of solvent/solution I can use for this compound.

Answer:
S1180 can be dissolved in 4% DMSO+corn oil at 1 mg/ml as a clear solution. When preparing the solution, please dissolve it in DMSO clearly first. You can sonicate and warm this compound in water bath at about 45 degree to help dissolving. Then dilute with corn oil.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
