Antibodies are an essential immune system component B-cells produce to neutralize pathogens such as bacteria, viruses, and toxins. With the development of antibody engineering services, scientists have been able to modify the structure and function of antibodies to create novel therapeutics with improved specificity, potency, and safety. This blog will provide an overview of Antibody Engineering Services and their applications in the biopharmaceutical industry.
What Are Antibody Engineering Services?
Antibody engineering services refer to a range of techniques that enable scientists to modify the structure and function of antibodies for therapeutic purposes. These techniques include antibody humanization, affinity maturation, bispecific antibody engineering, and conjugation.
Antibody Humanization
One of the major challenges in using antibodies as therapeutics is that they are derived from non-human species, such as mice or rabbits, which can trigger an immune response in human patients. To overcome this limitation, scientists have developed antibody humanization techniques, which involve replacing the non-human regions of the antibody with human counterparts while retaining the antigen-binding specificity. This process reduces the likelihood of an immune response and increases the half-life of the antibody in circulation, making it more effective as a therapeutic agent.
Affinity Maturation
Affinity maturation is another antibody engineering technique that aims to improve the binding affinity of an antibody to its target antigen. This technique involves generating a large library of antibody variants and screening and selecting those with the highest affinity to the target antigen. The selected antibodies can then be optimised using site-directed mutagenesis and protein engineering techniques to enhance their binding affinity and specificity.
Bispecific Antibody Engineering
Bispecific antibodies are engineered to bind to two different antigens, allowing for the targeted delivery of therapeutics to specific cells or tissues. This technique combines two different antibody molecules to create a single molecule with two distinct binding sites. Bispecific antibodies can target multiple disease pathways or redirect immune cells to attack cancer cells.
Antibody Conjugation
Antibody conjugation is the process of attaching other molecules to the antibody to enhance its therapeutic properties. For example, antibodies can be conjugated to drugs, radioisotopes, or toxins, allowing for targeted delivery of these molecules to specific cells or tissues. This technique has been used to develop antibody-drug conjugates (ADCs) that have shown promising results in cancer treatment.
Applications of Antibody Engineering Services
Antibody Engineering Services have revolutionized the biopharmaceutical industry, providing a range of therapeutic options for various diseases. Some of the key applications of antibody engineering services include:
- Cancer Treatment: Antibodies engineered for cancer treatment include monoclonal antibodies, bispecific antibodies, and antibody-drug conjugates. These therapies have shown promising results in clinical trials, with some already approved for patient use.
- Autoimmune Diseases: Antibody engineering services have been used to develop therapies for autoimmune diseases such as rheumatoid arthritis and psoriasis. These therapies target specific cells or proteins involved in the immune response.
- Infectious Diseases: Antibody engineering services have been used to develop therapies for infectious diseases like HIV and influenza. These therapies work by blocking the ability of the pathogen to infect cells or by targeting infected cells for destruction by the immune system.
