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.

C-reactive protein (CRP), an annular (ring-shaped), protein found in blood plasma. It is thought to assist in complement binding to foreign and damaged cells and enhances phagocytosis by macrophages.

A ball and stick + ribbons model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.

Aromatase (estrogen synthase) enzyme. Protein responsible for the key step in the synthesis of estrogens. 3D illustration. Cartoon representation.

Rapamycin, also known as sirolimus is a macrolide compound that has immunosuppressant functions and prevents transplant rejection through the inhibition of the protein complex mTORC1.

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.

Rendered coronavirus/2019-nCoV single-stranded RNA, built from experimentally determined Ebola virus crystal structure. Color symbols - bluewhite=carbon, pink=oxygen, lightblue=nitrogen, white=hydrogen, lavender=phosphorus

3d rendering of gold nanoparticles conjugated inside of the construction from DNA of a covalently closed cube-like molecular complex

Glucose-6-phosphate dehydrogenase (G6PD) protein. Enzyme of the pentose phosphate pathway that generates co-enzyme NADPH. 3D illustration.

Frost on cow parsley seed head. Heavily post processed to give an ethereal glow.

PKM2 plays key roles in reprogramming cancer cells from energy production to growth (Warburg Effect). The dimeric form of the enzyme is not only less active in glycolysis but can also move into the nucleus to promote the transcription of other cancer-causing genes. A substrate analogon (red) is bound to the active site. PKM2 is a target for anti-cancer therapies. PDB entry: 6WP3.

A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin. Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease. Isolated on white.
