Antigens, as is known, are the main components of all organisms. Unlike other immune molecules, they are foreign to the body. Among the huge variety of antibodies and antigens, flagellar antibodies, or flagellar antibodies, have their own unique structure. It is this structure that determines their specificity, immunological reactivity and the structure of cell membranes. The flagellum is located in a bacterial cell. What are flagella? These are filaments located in the planktonic cell and are proteins and are part of the cytoplasm. Compressed near the base, they are blown-shaped organs. A characteristic feature of flagella is the presence of a tubular internal channel (phylla), encircling the cis-helix and the tube, due to which the protein flagellum has the same structure as the cytoplasmic axis. A similar tubular channel is also present in the cytoplasm near the center of the cell, and for this reason it is called cannon grooves. In many organisms, this organ is also hereditary and is passed on from generation to generation.
