Developing improved immunoassays for paralytic shellfish toxins: The need for multiple, superior antibodies

► Paralytic shellfish toxins in seafood can cause human illness. ► Improved detection methods are necessary to protect consumers and industry. ► No single antibody reacts to the >20 congeners with respect to their toxicity. ► Antibody reactivities can be screened by surface plasmon resonance biosensors. ► A multiplexed antibody assay could lead to improved detection.
