The default ladder can be used as the ladder forwells on the plate, can be applied to all of the plates in the opencollection, or can be saved as the default ladder in a new assay.To set a specific ladder on a plate as the default ladder for the plate:1 With the plate data file open, select Analysis AnalysisSettings to open the Assay Analysis Window, and then click thePeak Find Tab.2 Under Well Peak Find Settings, in the Well drop-down list,select the ladder that will be defined as the default ladder.3 Click the Save as Default Ladder button.
