Determining effective drug concentrations for selection and counterselection genetics in Drosophila melanogaster

Abstract

Summary: We recently integrated into fly genetics a set of four selection and two counterselection markers and their corresponding drugs that can be used individually or in combination. These markers eliminate the need to visually screen progeny. Before using these markers in new genetic backgrounds, effective selection/counterselection concentrations should be established for each marker/drug combination. This protocol describes how to set up, perform, and analyze a drug titration curve to determine the effective selection/counterselection drug concentrations for their corresponding markers.For complete details on the use and execution of this protocol, please refer to Matinyan et al., 2021.
