Introduction

Recombinant human DKK-1 protein is a high-quality recombinant protein produced for research use, supporting cell culture, organoid growth, and in vitro biological studies with reliable activity and consistency.

Background

Dickkopf-Related Protein 1 (DKK1) is a secreted antagonist of the canonical Wnt/β-catenin signaling pathway. By inhibiting Wnt receptor activation, DKK1 regulates embryonic development, cell fate determination, and tissue patterning, and is widely used to induce differentiation or suppress stemness in developmental and stem cell research.
