Recombinant protein expression is a biotechnological process used to produce proteins by inserting a gene of interest into a host organism, typically bacteria, yeast, or mammalian cells. This gene encodes the desired protein, which is then expressed using the host's cellular machinery. The process involves several key steps: cloning the gene into a vector, transforming the host cells with this vector, and finally inducing protein expression under specific conditions.
Once the protein is expressed, it can be purified from the host cells using various techniques such as affinity chromatography. This method is crucial for producing proteins for research, therapeutic use, and industrial applications. Recombinant proteins can include enzymes, hormones, antibodies, and more, making this technique a cornerstone of modern biotechnology.
