Chlorophenol red is a pH indicator. It is used as an optical transducer of acetyl cholinesterase inhibition by the analytes. Chlorophenol red is also used to selectively determine chlorine dioxide in drinking water. It has been used in the novel assay to detect transformed protoplast-derived Zea mays colonies on Phosphinothricin (PPT).

The relaxin-3 neuropeptide activates the relaxin family peptide 3 (RXFP3) receptor to modulate stress, appetite, and cognition. RXFP3 shows promise as a target for treating neurological disorders, but realization of its clinical potential requires development of smaller RXFP3-specific drugs that

Detecting bacteria is important in the fields of human health, environmental monitoring, and food safety. Foodborne pathogens alone are estimated to cause 420 000 deaths annually, with low-income regions affected most. Despite improvements in bacterial detection, fast, disposable, low-cost, sensitive, and
