Antibodies produced by a group of identical B-cells against a single epitope of an antigen is called
polyclonal antibodies
monoclonal antibodies
anti- hapten antibodies
somaclonal antibodies
B.
monoclonal antibodies
Monoclonal antibodies are the antibodies produced by a group of identical B- cells that are all clones of a unique parent cells. They are monospecific antibodies, that is, they react against a single epitope of an antigen.
Polyclonal antibodies are antibodies that are secreted by different B cell lineages within the body. They are a collection of immunoglobulin molecules that react against a specific antigen, each identifying a different epitope.
Anti - hapten antibodies are essential for diagnostic and therapeutic applications of human health. They enable the detection of small molecules with a series of immune assays, such as ELISA.
