Improvement of the Lectin-Antibody Enzyme Immunoassay of the Alphafetoprotein Carbohydrate Chain for Automation with the Enzyme Immunoassay Robot

Abstract

The lectin-antibody enzyme immunoassay of the alphafetoprotein-L3 carbohydrate chain, a tumor marker of liver cancer, has not been automated. We improved the technique of the assay for automation. Consequently, alphafetoprotein-L3 and total alphafetoprotein were detected with two lectins using an automatic paramagnetic bead handling robot. This indicates that the improved method is potentially applicable to the automated enzyme immunoassay robot.
