Recombinant human Midkine protein, fused to a His-tag at the N-terminus, is expressed in Escherichia coli and purified using conventional chromatography . The protein consists of amino acids 21-143 of human Midkine and has a theoretical molecular weight of approximately 15.7 kDa . The His-tag facilitates purification and detection of the protein.
Midkine is pleiotropic, capable of exerting various biological activities such as:
It binds to cell-surface proteoglycan receptors via their chondroitin sulfate (CS) groups, regulating processes like inflammatory response, cell adhesion, cell growth, cell survival, tissue regeneration, cell differentiation, and cell migration .
Recombinant human Midkine protein is used in research to study its role in various biological processes and its potential therapeutic applications. It is particularly valuable in studies related to:
