Purity: ≥95%

Product Details

Biological Activity

xStAx-VHLL is a selective peptide-based β-catenin Degrader (PROTAC®). Comprises a β-catenin-targeted stapled peptide, xStAx, linked to a VHL-binding peptide. Reduces β-catenin levels in HEK293T cells and colorectal cancer cell lines. Selectively degrades β-catenin over other Wnt signaling pathway components. Inhibits tumor growth in APCmin/+ mice, with constitutively active Wnt signaling, and reduces survival of patient-derived colorectal cancer cell organoids. β-catenin antibodies validated for Simple Western™ (automated Western Blot) instruments and Western Blot also available: Catalog # AF1329 and NBP1-54467.
