Verified step by step guidance

Understand the concept of antibodies: Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

Learn about polyclonal antibodies: Polyclonal antibodies are a mixture of antibodies produced by different B cell clones in response to an antigen.

Recognize the diversity of polyclonal antibodies: Each B cell clone produces antibodies that recognize different epitopes on the same antigen, leading to a diverse set of antibodies.

Contrast with monoclonal antibodies: Monoclonal antibodies are produced by a single B cell clone and recognize a single epitope on an antigen, making them identical in structure and function.

Identify the characteristic of polyclonal antibodies: The key characteristic is that they are produced by multiple B cell clones, allowing them to recognize multiple epitopes on an antigen.
