Quantification of Extracellular Ammonium Concentrations and Transporter Activity in Yeast Using AmTrac Fluorescent Sensors
Authors:  Cindy Ast, Wolf B. Frommer, Guido Grossmann and Roberto De Michele, date: 01/05/2015, view: 4259, Q&A: 0
AmTracs are the first example of “activity sensors”, since they report the activity of ammonium transporters by means of fluorescence readout in vivo (De Michele et al., 2013). AmTracs are based on a single fluorescent protein, a ...
