Midkine is a heparin-binding growth factor, originally reported as the product of a retinoic acid-responsive gene during embryogenesis, but currently viewed as a multifaceted factor contributing to both normal tissue homeostasis and disease development. Midkine is abnormally expressed at high levels in various human malignancies and acts as a mediator for the acquisition of critical hallmarks of cancer, including cell growth, survival, metastasis, migration, and angiogenesis. Midkine Protein, Mouse, Recombinant (His) is expressed in E. coli expression system with N-His tag. The predicted molecular weight is 14.03 kDa and the accession number is P12025.
