Successful flow cytometric analysis depends on adequate sample preparation (see Chapters 30-31), appropriate selection of probes or markers (see Subheading 2.), instrumentation, and data display and analysis. Each of these areas is interrelated and requires adequate attention to avoid the introduction of artifacts and misinterpretation of results. Flow cytometers tend to be excessively complicated and require a skilled operator for alignment and calibration, though manufacturers are introducing more compact, user-friendly data acquisition and image processing systems. 

The fragments were aligned using genetic markers, and their lengths were estimated by their electrophoretic mobilities.77 The time-of-entry map has been added on a distorted scale in Fig. 26-4B. There are, on the average, 46.4 kb of DNA per minute, but this amount varies around the chromosome between 38 and 61 kb / min. 

Align the autoradiogram with the gel and mark the position of the wells on the film. Identify the RNA size marker bands on the autoradiogram (three of them in one lane). The instructor will provide you with the information that you need to determine the number of nucleotides that each standard RNA marker contains. 

When this approach is applied to Series 3 to provide Tick Mark Labels, you ll get two superimposed data labels at each x value (for example, 12 and 11.8 if you chose to display values.) This means that you ll have to select one of the two labels and delete it, then select the other label and edit it. A better way to add the data labels is to add a fourth data series with a single point for each tick mark in this example, select C20 D20,C23 D23,C26 D26,C29 D29 and Copy, add this as a new series. Series 4, using Paste Special, then format the series to set both Line and Marker to None. Then add data labels, either values (Y values) or labels (X values), to this series. Change the Alignment of the data labels to Above. Edit the data labels individually, replacing them with the desired text.
