Half-life Extension Service by Genetic Manipulation

For Research Use Only. Not for Clinical Use.

With the development of site-directed mutation of proteins, genetic engineering is used to extend the half-life of therapeutic proteins or peptides by replacing one or more key amino acids. This strategy is very simple and convenient, completely avoids the process of modification in vitro, and directly expresses the purified target protein drug molecules, which has great application potential. Creative Biolabs is always committed to providing the scientific community with the latest and most comprehensive services in the field of drug discovery. Our scientists are confident in offering the best half-life extension service by genetic manipulation for the development of novel drugs.

Introduction of Half-life Extension Service

Half-life Extension Service by Genetic Manipulation

Antibodies, hormones, and interferons suffering from short half-life are endogenous protease degradation in vivo. However, many proteases are restriction enzymes that recognize and cut protein or at a particular site. Therefore, suitable genetic manipulation will lead to the changes in protein primary sequence and protect protein drugs from enzymolysis. Hence the amino acid mutation caused by genetic engineering can enhance the pharmacokinetic properties of the protein with maintaining its activity intact.

Applications of Half-life Extension Service by Genetic Manipulation

Half-life Extension Service by Genetic Manipulation 2

Recent research has shown that mutation in one or more genes has successfully generated a few long-acting counter parts of native short-acting peptide therapeutics. Alteration of one or more amino acids in a peptide chain is used to prolong the half-life of proteins, and most of them obtained an extension of half-lives by more than ten times.

Lately, studies suggest that a single amino-acid substitution can make a molecule highly protease resistant in vivo. The point mutation of interferon has been used in long-acting interferon beta preparation. While genetic manipulation based improved somatropin formulation was entered phase 1 trial. Many achievements supported that point mutation has surfaced as a new technology for protein pharmacokinetic enhancement and is widely used in therapeutic protein research. As a novel, convenient, and one-stop half-life extension strategy, genetic manipulation bears great expectations of the drugs development market.
