This book (on CD-ROM) takes an entirely novel approach as it guides you through the different applications of flow cytometry to mammalian biology. Rather than presenting you with text illustrated with static pictures, the book supplies files of the raw data so that you can experiment dynamically with the data for yourself.

 In flow cytometry, measurements of up to seven parameters are made on individual cells. Typically, from a single sample, data may be recorded on 10,000 or more cells. These data (known as listed data) are written to the hard disc of the computer. They can be run through the analysis program as often as the experimenter wishes. On each run, different methods of analysis can be tested; it is as if identical cells were being rerun each time through the flow cytometer. On the CD-ROM, 173 of these files have been supplied for you to analyse. They come from seventeen laboratories in seven different countries.

 The accompanying text describes the major features of the analysis of data from each application. Guidance is given about how to proceed. You are then free to experiment with the analysis for yourself. Some of the pitfalls are also described and for a few applications, files of misrecorded data have been included to illustrate these pitfalls.

 I use WINMDI (supplied with the CD-ROM) for data analysis, but you can use any program which reads FCS data files.

To give you a flavour of the book, I have included Chapter 7 on the quantification of cell death (including apoptosis) together with the first seven data files from the section on apoptosis.
