About Recombinant Proteins

Recombinant DNA technology used to express proteins has proven to be one of the most powerful tools for expanding our knowledge in biological sciences. The production of recombinant proteins generally requires the use of an expression vector or construct consisting of a plasmid and a gene insert. The plasmid usually contains two transcription factors one to drive the expression of the gene of interest the other to drive the expression of the resistance gene. Recombinant protein technology has provided important tools for scientists to achieve breakthroughs in medical research and treatments for a wide variety of disease states such as cancer, autoimmune and diabetes. 

Mammalian Protein Expression

In order to provide the most biologically active proteins, that most resemble the native structure including post translational modifications such as glycosylation, Leinco usually uses mammalian expression systems for producing recombinant proteins.
