Title
(EN) FLUORESCENT AQUATIC BIOASSAY AND PROCEDURE
(FR) PROCEDE ET DISPOSITIF D'ANALYSE BIOLOGIQUE AQUATIQUE PAR FLUORESCENCE
Abstract
(EN)
The present invention relates to a novel assay for determining levels of toxicants in aqueous environments, preferably in water supplies. The present invention also relates to a method for utilizing the assay to test the level of toxicants in an aquatic source. Further embodiments of the present invention relate to a test kit embodying the assay of the present invention, and the enzymatic modification of a substrate to produce a fluorescent product.
(FR)
Dispositif d'analyse pour déterminer des taux de matières toxiques dans des milieux aqueux, de préférence dans des systèmes d'approvisionnement en eau. L'invention porte également sur un procédé utilisant ce dispositif d'analyse pour vérifier le taux de matières toxiques dans un milieu aqueux. L'invention porte en outre sur un kit d'analyse pour la mise en ÷uvre du procédé et sur la modification enzymatique d'un substrat pour obtenir un produit fluorescent.
