Microcystins (MCs) form a group of cyclic heptapeptides produced by common cyanobacteria (blue green algae) and cause both acute and chronic toxicity. For immunization purposes, an amino derivative of MC-LR was prepared before coupling to BSA. Among the different monoclonal antibodies produced, mAb MC159 was selected due to its broad specificity to develop(More)
Staphylococcus enterotoxin B (SEB) is one of several toxins produced by the gram positive bacterium Staphylococcus aureus. SEB is a major cause of food poisoning and represents a significant biological threat with regard to bioterrorism. A rapid, sensitive, and specific method is required to monitor food and water in cases of both natural and intentional(More)
Microcystins (MCs), a group of cyclic heptapeptides produced by common cyanobacteria (blue green algae), cause both acute and chronic toxicity. Due to their toxicity, constant monitoring in drinking water, recreational waters as well as other potential exposure through ingestion of contaminated sea food, is very important. In this context, an(More)
Occupational exposure to polycyclic aromatic hydrocarbons (PAH) is associated with an increased risk of urothelial carcinoma (UC). FGFR3 is found mutated in about 70% of Ta tumors, which represent the major group at diagnosis. The influence of PAH on FGFR3 mutations and whether it is related to the emergence or shaping of these mutations is not yet known.(More)
