Ordering Information

Biological Activity

iCRT3 is a potent Wnt/β-catenin signaling antagonist that inhibits β-catenin/TCF-mediated transcription with an IC50 ofin STF16-luc reporter assays. By directly interfering with the interaction between β-catenin and TCF transcription factors, iCRT3 disrupts downstream Wnt pathway target gene expression. Consequently, this compound suppresses cell proliferation, attenuates β-catenin-driven oncogenic phenotypes, and induces apoptosis in Wnt-dependent cancer cell models. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
