Two kinds of custom antibodies are available-monoclonal or polyclonal. Polyclonal antibodies are created in response to a mixture of epitopes on complex injected antigenic material; monoclonal antibodies are produced by a hybridoma strain, which is created from fusion of an immortal tumor cell line with a single B lymphocyte, and thus respond to a single specific epitope.Your initial version of the influenza assay kit was a great success.
