Health-care workers, laboratorians and overdose prevention centers rely on commercial immunoassays to detect the presence of fentanyl; however, the cross-reactivity of fentanyl analogs with these kits is largely unknown. To address this, we conducted a pilot study evaluating the detection of 30 fentanyl analogs and metabolites by 19 commercially…[Read more]

We further demonstrated that the expression of PSY was negatively regulated by CsPHL3 and high Pi. It is concluded that CsPHL3 is a Pi starvation response factor that negatively regulates carotenoid metabolism by modulating the expression of carotenogenic genes. Establishment of the CsPHL3-CsLCYb1 network provides new valuable knowledge of the…[Read more]
