Reconstitution Protocol :Reconstitute at 0.1 mg/ml in sterile PBS

Scientific Background :Midkine and its functionally-related protein Pleiotrophin (PTN), are heparin-binding neurotrophic factors that signal through the same receptor. Midkine is involved in a number of biological processes including the migration of neutrophils, inflammatory leukocytes, macrophages, neuronal cells, and osteoclasts. Midkine is a basic, non-glycosylated polypeptide that contains five intra-chain disulfide bonds. There is 87% identity between the human and murine Midkine and approximately 50% identity between human Midkine and human PTN with the conservation of all 10 cysteines.

Sample Cell Assay Data :The ED (50) was determined by the dose-dependent proliferation of AsPC-1 cells and was found to be <0.5ng/mL.

Purity :Recombinant Human Midkine (NEGF2) resolved on a 17% SDS-PAGE gel under reducing conditions and stained with Coomassie Brilliant Blue G-250
