Half-life extension service by chemical modifications is a specialized biopharmaceutical approach designed to enhance the stability and therapeutic efficacy of biologics, including proteins, peptides, and antibodies, by prolonging their half-life in the body. This innovative service is particularly valuable in addressing challenges associated with the short-lived nature of many therapeutic molecules, which often require frequent administration to maintain effective therapeutic levels. By extending the duration of action of these biologics, the half-life extension process minimizes dosing frequency, significantly improving patient compliance and overall treatment convenience.
