This paper gives a method for determining the presence of the toxin from Bt var. tenebrionis and Bt var. kurstaki on clay and silt-sized particles from soil. Toxin was bound to soil and a buffer was used to block non-specific antibody binding. Antibody with a fluorescent marker was added to the suspension. Flow cytometry was used for detection.
They did not use real soil. There was considerable cross-reactivity potential, especially in environmental matrices. Authors say that it is more sensitive and rapid than ELISA.
