Recombinant protein

Recombinant proteins are artificially synthesized proteins. They are made by using recombinant DNA technology. Scientists insert the gene encoding the desired protein into a suitable expression system, such as bacteria, yeast or mammalian cells. The host cells then produce the protein under the control of the inserted gene. Recombinant proteins are widely used in medical and research fields. For example, they can be used as therapeutic agents to treat diseases like diabetes (insulin is a well-known example) or as diagnostic tools to detect specific biomarkers.
