A High-Throughput Assay for Detection and Monitoring of Endocrine-Disrupting Chemicals in Water Sources
Posted Feb 20 2013 7:00pm
Description of Invention: This technology describes a high-throughput, fluorescence-based method to detect endocrine-disrupting chemicals (EDCs) in water sources.
There is growing awareness that a wide variety of synthetic and natural compounds that may lead to adverse health effects are present in water sources, such as streams, wells, and ground water; however, these compounds are often difficult to measure and thus are not commonly monitored. Even low concentrations of these compounds are of concern, as they may have biological effects at concentrations of parts per billion (PPB) or less. The presence of EDCs in the environment, in particular, is under examination for potential adverse effects on human health and on wildlife, such as cancer, immune suppression, impaired fertility, and increased incidence of diabetes and obesity.
Inventors at NCI have discovered a novel assay methodology for detecting endocrine EDCs in contaminated water. The assay utilizes fluorescently-labeled nuclear receptors in a high-throughput, cell-based format, and has the capability to detect very low concentrations of EDCs in water or other liquid samples. The inventors have already demonstrated proof of concept for this technology by using this assay to test for the presence of glucocorticoid and androgen receptor disruptors in water samples from 14 U.S. states, and also plan future studies for other types of EDCs. A product or service based on this technology could fulfill an unmet need for a high-throughput, rapid method for screening water samples for contaminants with potential endocrine-disrupting effects.
Applications: Product or service for screening and detection of endocrine disrupting chemicals (EDCs) in samples from water sources and waste water.
Rapid results - one day or less from sample retrieval to result
Detects very low concentrations of EDCs
Readily adaptable for use with a variety of endocrine receptor targets
High-throughput format allows testing of many samples at once, with multiple types of endocrine receptor targets
Tests for activity rather than a specific chemical, therefore can detect many variants modified in the environment
