Definition | BDS-PAH CALUX. Analytical method of BioDetection Systems (BDS): Bioassay detection of ArH-activity coupled to presence of PAH. The samples were freeze dried, extracted with ASE (accelerated solvent extraction) with acetone/hexane (10%/90% v/v), restituted in DMSO (dimethylsulfoxid) and subsequently measured in the CALUX bioassay. The PAH CALUX bioassay comprises a rat hepatoma cell line (H4IIE), incorporating the firefly luciferase gene coupled to Dioxin Responsive Elements (DREs) as a reporter gene. Following binding of PAH compounds to the intracellular dioxin receptor, the ligand-receptor complex binds to and activates the DRE followed by expression of PAH and luciferace. By addition of substrate for luciferase, light is emitted which is measured in a luminometer. The amount of light produced is proportional to the amount of ligand-specific receptor binding, which is benchmarked against the reference compound: Benzo[a]pyrene (B[a])P). The amount of light of the samples is interpolated in the curve to obtain the reference equivalents.
