It is indeed almost impossible to count the original papers, reviews, abstracts, and meeting communications, and talks in which an immunologist, from undergraduate students to Nobel laureates, has measured a parameter of interest at the single cell, organelle, or even molecular level using one of the sophisticated cytometric technologies that we are discussing here. Unfortunately, measuring what happens in a biological system, starting from the single cell level (that is, cyto for cell, metry for measure) is not as simple as it seems, and can lead to results that are not always optimal. In most cases, flow cytometry is relatively easy to use, and often even a brief trainingif not the simple reading of a bench manual or a rapid glance over a protocolenables a researcher to use a flow cytometer and start producing data. As we have already pointed out in ref. [1], paradoxically, this is a main weakness of cytometry. Indeed, a well-trained cytometrist can often identify in published papers experimental aspects or data that must be improved, if not fully redone. The importance of adequate controls, correct compensation, clean and well monitored sorting strategies, correct data analysis, presentation, and interpretation, and the description of the methods used cannot be stressed Bisacodyl enough. It is for these reasons, a few years ago, following enthusiastic discussions at the European Congress of Immunology held in Vienna, September 2015, and Bisacodyl under the guidance of Professor Andreas Radbruch (at that time Chair of the Executive Committee of theEuropean Journal of Immunology(EJI) and currently EFIS President), that the Editorial Team of theEuropean Journal of Immunologyfelt that it was worthwhile to offer our community guidelines for the correct use of cytometric techniques in the field of immunology. For this, we were able to put together a large team of renowned experts who prepared a first collection of protocols of interest for our community. In the previous version of the guidelines, which was authored by 236 scientists from 194 institutions spread across the world, we focused on core aspects including advice and best practice regarding Bisacodyl how to study complex cell phenotypes, the type or amount of molecules produced or secreted after Bisacodyl activation from the cell human population of interest, signaling processes, differentiation, proliferation, cell death, cytotoxic activities, cellcell relationships, the features of S1PR4 organelles such as mitochondria, the different types of response induced against tumours, transcription element activity, quantification of soluble molecules, drug uptake, and rare events, not forgetting the parts related to the choice of reagents, the preparation and/or storage of the cells under analysis, the overall experimental strategy, and finally, the analysis of data. But a good scientist knows that all attempts, including those collected in extensive recommendations like ours, can and must be improved. Accordingly, we asked for feedback within the published recommendations and received essential comments, fresh ideas, and suggestions for this fresh version, and here we are! With this updated version, we have tried to ameliorate and upgrade several parts and the reader will find more standardized sections that should make it better to navigate throughout the text that right now features novel suggestions and pitfalls to avoid. Importantly the phenotyping sections are clearly divided into human being and murine sections, again to help the reader find the section.
