Polyclonal antibodiesgenerally an immune response activates a number of different plasma cells which can produce only one type of antibody.Each individual antibody will have its own affinity for antigen and specificity for the antigen.The sum of these antibodies that recognize a particular antigen is called Polyclonal antibodies because they arise from many different B cells (plasma cells).
