| Formulation |
Lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4. |
| Solubility |
It is recommended to reconstitute the lyophilized Midkine Mouse in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity |
Greater than 95.0% as determined by HPLC and SDS-PAGE. |
| Description |
Midkine Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 120 amino acids and having a molecular mass of 13.3kDa.The Midkine Mouse is purified by proprietary chromatographic techniques. |
| Protein Background |
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. |
| Expression host |
Escherichia Coli. |
| Synonyms |
NEGF-2, Neurite Growth-Promoting Factor 2, MK, Neurite outgrowth-promoting protein, Midgestation and kidney protein, Amphiregulin-associated protein, ARAP, Neurite outgrowth-promoting factor 2, FLJ27379, Midkine, MK1, NEGF2. |
| Reagent Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| Stability |
Lyophilized Midkine Mouse although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Midkine Mouse should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles. |
