Abstract
Cyclomaltoheptaose (β-cyclodextrin, β-CD) is a promising compound for application in various industrial fields because of its ability to entrap various compounds into its hydrophobic cavity. A monoclonal antibody (A7) to β-CD was generated by using a conjugate of glucosaminylmaltosyl-β-CD and bovine serum albumin as an antigen. The A7 monoclonal antibody was IgM/κ and reacted with β-CD with high specificity. The epitope recognized by the A7 monoclonal antibody seemed to be located on the secondary hydroxyl groups of the rim side of the β-CD molecule. The dissociation constant of the complex of β-CD and the immobilized A7 monoclonal antibody was determined to be 1.2 × 10-4 M. A competitive ELISA using the A7 monoclonal antibody enabled determination of β-CD and its derivatives with a detection limit of 0.05 μM. This immunoassay was useful to determine β-CD in biological fluids such as human plasma and urine after appropriate pretreatment of the samples.
