Recombinant proteins have become a fundamental aspect of modern biotechnology, profoundly impacting various domains such as medicine, research, and industry. This article aims to provide a concise overview of recombinant proteins, including their definition, production methods, and wide-ranging applications.

Recombinant proteins are artificially engineered proteins created by introducing a specific DNA sequence, typically sourced from one organism, into a different host organism. This process enables the production of proteins that are not naturally synthesized within the host organism. The desired protein's DNA sequence is inserted into a vector, serving as a vehicle to transfer the DNA into the cells of the host organism. Subsequently, the host's cellular machinery translates the DNA sequence into the desired protein.
