Question

Quizplus · Accepted Answer

Monoclonal antibodies are produced from a single type of B cell, resulting in highly specific binding to a single epitope on an antigen. Affinity-purified antibodies are those that have been purified based on their binding affinity, but this does not necessarily imply specificity for a single epitope. Polyclonal antibodies are produced from multiple types of B cells and can bind to multiple epitopes on an antigen. Multiclonal is not a recognized term in the field of immunology.
