Product Description |
Recombinant Human Midkine Protein is expressed from E.coli with His tag and Avi Tag at the N-Terminus.It contains Val21-Asp143. |
Product Background |
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. |
