A therapeutic antibody is a laboratory-produced antibody designed to target specific proteins in the human body, offering precision treatment for various diseases — from cancer and autoimmune disorders to infectious diseases. Therapeutic antibodies harness the immune system’s ability to recognise and neutralise harmful antigens, allowing for highly specific interventions with fewer side effects compared to conventional treatments. Through specialised antibody services — including screening, engineering, optimization, and validation — therapeutic antibodies are developed to maximise their binding specificity, stability, and safety for human use. This powerful class of biologics enables treatments that directly address disease mechanisms, improve patient outcomes, and pave the way for personalised medicine. Therapeutic antibodies have transformed modern healthcare by offering targeted therapies, improved efficacy, and reduced systemic toxicity. Their development represents a key focus area in biotechnology and drug discovery, bridging advanced science with clinical applications to offer hope for complex and chronic conditions.
