- Antibodies are glycoproteins with a molecular weight of approximately 160 kDa.
- They are produced by immune cells and are vital components of the immune system, helping to protect the body from foreign particles such as viruses and bacteria.
- A typical antibody has a Y-shaped structure, consisting of two heavy chains and two light chains connected by disulfide bonds (-S-S-).
- Disulfide bonds are formed between the cysteine residues of the heavy and light chains.
- The molecular weight of each light chain is about 25 kDa, while each heavy chain weighs around 55 kDa.
