General description

Recombinant human Midkine is a 13.4 kDa protein containing 123 amino acid residues including five intra-molecular disulfide bonds.

Application

Midkine human has been used in cell viability assay and cell proliferation assay to determine its association with EMT (epithelial-mesenchymal transition) and gemcitabine resistance in biliary tract cancer.

Biochem/physiol Actions

Midkine (MK) and its functionally-related protein Pleiotrophin are heparin-binding neurotrophic factors that signal through the same receptor, known as anaplastic lymphoma kinase (ALK). MK (midkine) plays an important regulatory role in epithelial-mesenchymal interactions during fetal development and in postnatal lung development. MK chemoattracts embryonic neurons, neutrophils and macrophages. Signaling through the ALK (anaplastic lymphoma kinase) receptor MK exerts angiogenic, growth and survival activities during tumorigenesis. MK is expressed predominantly during midgestation in the brain and several other organs and is down-regulated at birth.

Physical form

Lyophilized from 0.4x PBS, pH 7.4.

Preparation Note

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
