Can calcium be leached from bones by the phosphorus in soft drinks? Q: Iâve heard that calcium can be leached from bones by the phosphorus in soft drinks. Is that true? Soda is definitely bad for your bones, but scientists havenât yet figured out if the phosphoric acid found in cola is partly to blame.
Secondary antibody is especially efficient in immunolabeling. In immunolabeling, primary antibody's Fab domain binds to an antigen and exposes its Fc domain to secondary antibody.Then, secondary antibody's Fab domain binds to the primary antibody's Fc domain.Since antibody's Fc domain is constant within the same animal class, only one type of secondary antibody is required to bind to many types of primary antibodies.hen, secondary antibody's Fab domain binds to the primary antibody's Fc domain. Since antibody's Fc domain is constant within the same animal class, only one type of secondary antibody is required to bind to many types of primary antibodies.
Antibody genes also re-organize in a process called class switching that changes the base of the heavy chain to another, creating a different isotype of the antibody that retains the antigen specific variable region. This allows a single antibody to be used by several different parts of the immune system. Production of antibodies is the main function of the humoral immune system.
