Human Midkine Protein

• Catalog Number: orb427096
• Category: Proteins
• Description: Recombinant of human Midkine protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Purity: Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
• Solubility (25°C): It is recommended to reconstitute the lyophilized Midkine in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

• Source: Escherichia Coli
• Biological Activity: Determined by its ability to chemoattract human neutrophils using a concentration range of 0.1-10 ng/ml corresponding to a specific activity of 100,000-10,000,000IU/mg.
• Storage: Stability: Lyophilized Midkine although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Midkine should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles
• Buffer/Preservatives: Lyophilized from a 0.2µm filtered concentrated solution in 1×PBS, pH 7.4.
• Alternative names: NEGF-2, Neurite Growth-Promoting Factor 2, MK, Neu
• Note: For research use only
• Application notes: Cytokines And Growth Factors
• Expiration Date: 6 months from date of receipt.
