Hu Midkine, 20 _g

Recombinant human Midkine (Hu MK) from STEMCELL Technologies is a heparin-binding growth factor supplied as a 20 µg lyophilized powder. Midkine signals through receptor tyrosine kinases such as RPTPζ, ALK, and integrins to drive neurite outgrowth, neuronal survival, chemotaxis of inflammatory cells, and angiogenic activity, supporting research into neural development, tissue repair, and tumor microenvironments.

The protein is expressed in E. coli and is intended for research use only. Reconstitute in sterile water or aqueous buffer containing 0.1% BSA to prepare a working stock, then store aliquots frozen at -20 °C; limit freeze-thaw cycles to preserve bioactivity for downstream in vitro chemotaxis and cell culture assays.

Typical laboratory applications include supplementing serum-free or defined media for neural stem cell culture and hepatocyte maintenance. The 20 µg single vial supports multiple small-volume experiments across standard bench workflows in academic and industrial cell biology programs.
