protein G−DNA conjugate an antibody to the intended area on the surface of bioassay chips or particles; 3d rendering
Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.

Medical Laboratory Research Background
Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.
A ball and stick model of Human Insulin. Isolated on black.
Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
