Monoclonal antibodies to potato, tomato, and eggplant glycoalkaloids and assays for the same

A hybridoma cell lines is described which produces and secretes a monoclonal antibody which selectively binds to the glycoalkaloids of potatoes, tomatoes, and eggplants, as well as their corresponding aglycones. Glycoalkaloids of potatoes, tomatoes, and/or eggplants in biological samples may be detected and quantified by contacting the sample with the antibodies to form a glycoalkaloid/antibody immunocomplex when the glycoalkaloids are present, which immunocomplex may then be detected. The monoclonal antibody may also be incorporated into kits for the detection and quantification of glycoalkaloids in plants, foods, and body tissues and fluids.
