Recombinant DNA Origin

Meaning

Recombinant DNA Origin, in the context of therapeutic agents, describes a substance, typically a protein or peptide hormone, that has been manufactured using recombinant DNA technology rather than being purified from natural biological sources. This process involves isolating the human gene for the desired hormone, inserting it into a host organism like bacteria or yeast, and then inducing the host to express and synthesize the protein in large quantities. The resulting product is structurally identical or highly similar to the endogenous human hormone, offering a reliable, scalable, and purer source for clinical use, such as with recombinant human growth hormone or insulin. This technological origin ensures consistent quality and eliminates the risk of contamination from human or animal sources.
