State College, PA (November 7, 2022) – INDIGO Biosciences, Inc. has received approval from the California Water Boards, State Water Resources Control Board, for the use of two of its bioassays in recycled water monitoring. INDIGO has been approved for the use of its Aryl Hydrocarbon Receptor (AhR) and Estrogen Receptor Alpha (ERα) bioassays as bioanalytical screening tools for Constituents of Emerging Concern (CECs) in recycled water.
“Both of these assays were developed by INDIGO’s in-house scientific team,” said Fred Marroni, INDIGO’s President and CEO, “and this approval highlights INDIGO’s scientific expertise in developing screening tools that can help protect the environment and human health. We look forward to developing additional bioassays that can help water boards and regulators everywhere monitor for contaminants that pose potential environmental and health risks.”
As part of the approval process, INDIGO submitted validation packages for both its AhR and ERα assays. Both validation packages demonstrated the utility of the bioassays for use as biological screening tools for CECs as set forth in California’s Recycled Water Policy. These assays are useful in screening for biological activity due to CECs such as estradiol, bisphenol A, nonylphenol, dioxin-like chemicals, polycyclic aromatic hydrocarbons, and pesticides.
