This study introduces the use of an IgA isotype aflatoxin (AF) specific
monoclonal antibody for the development of a highly sensitive Quartz Crystal
Microbalance (QCM) immunobiosensor for the detection of AF in inhibitory
immunoassay format. The higher molecular weight of IgA antibodies proved an
advantage over commonly used IgG antibodies in label free immunobiosensor
measurements. IgA and IgG antibodies with similar affinity for AF were used in
the comparative studies. Sensor surface was prepared by covalent immobilization
of AFB1, using self assembled monolayer (SAM) formed on gold coated Quartz
Crystal, with 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxy
succinimide (EDC/NHS) method using a diamine linker. Nonspecific binding to the
surface was decreased by minimizing the duration of EDC/NHS activation. Sensor
surface was chemically blocked after AF immobilization without any need for
protein blocking. This protein free sensor chip endured harsh solutions with
strong ionic detergent at high pH, which is required for the regeneration of the
high affinity antibody-antigen interaction. According to the obtained results,
the detection range with IgA antibodies was higher than IgG antibodies in QCM
immunosensor developed for AFB1.
