This module is aimed at those new to flow cytometry and those wanting to understand the basics of the technology before attending Module 2.  This can be taken as a standalone one day course or can be taken as a building block for the next module.   The course starts with an introduction to this quickly evolving technology, its importance and resources that are available.  One of the main aims of this course is to give the delegate a firm understanding of fluorescence, fluorochromes and the workings of a cytometer.  This is followed by talks on fluorescence compensation, sample preparation, basics of experimental design, data analysis and reporting your flow cytometry data.   It is highly recommended that all delegates attend Module 1 before attending Module 2, even those with years of experience in flow cytometry.  This is to ensure that all participants get the most out of the modules and to confirm that the basics of flow cytometry have been grasped before tackling more advanced topics in Module 2.
