Mitosis is a dynamic and stochastic process that has evolved to accurately segregate the geneticmaterialintotwodaughtercells, therebypreventinggenomicinstabilityandthe developmentofdisease. Mitosisisaphenomenallycomplicatedprocessthatinvolvesh- dreds, ifnotthousands, ofproteincomponentsandregulatorystepsthatoperateinboth spaceandtimetodrivecelldivision. Modernmethodsmakeitpossibletoaskformechan- ticprinciplesunderlyingthisbewilderingcomplexity. Themainpurposeofthisvolumeis toprovideanup-to-datecollectionofmethodsandapproachesthatareusedtoinvestigate themechanismofmitosisatthemolecularlevel. Whilemanyofthesemethodsarefocused onmammaliancells, wehave, whereappropriate, includedchaptersusingmodelorg- isms. We hope to capture both current approaches and the future direction of method development, withcontributionsfrombothestablishedresearchersandemergingyoung scientists. Thisbookisdesignedwithtwogeneralgroupsofreadersinmind: First, graduates- dentsandpostdoctoralresearcherswhoarebeginningworkforthe?rsttimeinamitosis laboratory. Second, researcherswhoarealreadyworkinginthemitosis?eldwhorequire a resource for both established and newly developed methodologies. To achieve this, the organization of this book developed into three general areas: First, we cover me- ods that can be used to inactivate your gene of interest, or deplete proteins of interest (chapters1 3). Second, welearnaboutspeci?cbiochemicalandmicroscope-basedme- ods (chapters 4 9). Third, we discover approaches to monitor and measure key mitotic processes(chapters9 20). Giventhecomplexitiesofmitosis, itseemshighlyprobablethat suchacombinationofimaging, biochemicalandgeneticmethodologieswillbecrucialto ourfutureunderstandingofmitoticregulation. I would like to thank all of the authors for their enthusiasm and effort in putting togetherthissetofmethods, aswellasallthemembersofmylaboratoryforproofreading and correcting the chapters and especially Sarah McClelland who read all the chapters atleasttwiceatvariousstages.
