Polyclonal antibodies are antibodies that are derived from different cell lines.
These antibodies are typically produced by immunization of a suitable mammal, such as a mouse or rabbit. An antigen is injected into the mammal. This induces the B-lymphocytes to produce IgG immunoglobulins specific for the antigen. This IgG is purified from the mammal?s serum.
Several lines of B-lymphocytes produce these antibodies. These antibodies have specificity for different epitopes.
By contrast, monoclonal antibodies are derived from a single cell line.
DiaPharma provides monoclonal antibodies for research use to the US market.
