The biological activity determined by a chemotaxis bioassay using human neutrophils is in a concentration range of 10-100 ng/ml.

More Info

  • Introduction

    Midkine (MK) is the product of a retinoic acid responsive gene, MK, and is a member of a family of heparin binding factors. It contains 121 amino acid residues including 10 conserved cysteine residues, all of which appear to be disulphide linked.
    Midkine is expressed during embryogenesis, showing an expression pattern that suggests functions in neurogenesis, cell migration, secondary organogenetic induction, and mesoderm-epithelial interaction.
    The widespread downregulation of MK in the adult human is reverted in a number of cancers, in which polypeptides are able to act as both transforming growth factors and promoters of angiogenesis.
    Midkine (MK), induces chemotaxis of human neutrophils and was found to trigger mobilization of intracellular calcium of these cells.
    Midkine induces histamine release from rat peritoneal mast cells with a rapid response in a dose dependent manner.
    Midkine is also a potent stimulator of collagen and glycosaminoglycan synthesis.

  • Synonyms

    Midkine, MK, Mdk.

  • Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

  • Stability

    Lyophilized Midkine Rat although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Midkine Rat should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.

  • Solubility

    It is recommended to reconstitute the lyophilized Midkine Rat in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
