ÖZTÜRK LAB: RECOMBINANT PROTEINS AND MONOCLONAL ANTIBODIES

The class of therapeutics called ”Biologics” include recombinant proteins, monoclonal antibodies, mRNAs, live cells, vaccines and recombinant viruses. Major biologics are monoclonal antibodies and recombinant proteins that are approved for the treatment of a variety of diseases, ranging from those that treat rare patients wirh rare but devastating genetic disorders to those treating hundreds of thousands of patients for some cancers and multiple sclerosis or even millions of patients for diseases such as asthma and rheumatoid arthritis.

Our laboratory is primarily interested in the exploration of home-designed recombinant proteins, monoclonal antibodies, and mRNAs for treatment of major diseases such as cancer and atherosclerosis. We select promising cell surface targets and design targeting tools such as ligands, soluble receptors and antibodies for targeted therapies.

We developed technologies such as monoclonal antibody production by hybridomas, recombinant protein production by synthetic genes in mammalian cells such as Hek293 and CHO, as well as protein purification by chromatography and biochemical characterization of proteins.

Antibodies and recombinant proteins offer a wide area of application in different domains of life sciences including medicine, pharmacy, veterinary medicine, microbiology, botaanic and agriculture. We welcome collaborations from all life science investigators and industrial partners for their needs in recombinant proteins and monoclonal antibodies.

Currently, we are producing monoclonal antibodies for diagnostic use in clinical pathology for cancer markers such as p53, p40, beta-catenin, Napsin A, cytokeratin 5 and PDL-1.  We are also producing chimeric proteins for engaging macrophages to eliminate atherosclerosis plaques.
