Recombinant human insulin. 3d cartoon model based on protein data bank
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.
