The protocols in this unit enable real-time intravital imaging of intracellular calcium concentration simultaneously in hundreds of neurons, or at the resolution of single synapses, as mice respond to sensory stimuli or perform behavioral tasks. Protocols are presented for implantation of a cranial imaging window to provide optical access to the brain and for 2-photon image acquisition.

In this chapter, we introduce the principles of confocal microscopy and discuss how the approach has become a mainstay in the biological sciences. We describe the components of a CLSM system and assess how modern implementations of the approach have further expanded the use of the technique. Finally, we briefly outline some practical considerations to take into account when acquiring data using a CLSM system. © 2018 by John Wiley &amp; Sons, Inc.</p>","PeriodicalId":11020,"journal":{"name":"Current Protocols in Cytometry","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/cpcy.39","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36242686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commercial implementations to date combine both hydrodynamic and acoustic focusing together to enable high precision analysis of a broad dynamic range of volumetric sample input rates up to an order of magnitude higher than is practical with hydrodynamic focus alone. This capability allows great flexibility in reducing assay time or modifying or eliminating concentration requirements or concentration steps in sample preparation protocols. It also provides a practical method for processing sub-microliter volumes using sample dilution. In order to take full advantage of this dynamic range, it is necessary to understand the fundamental benefits and limitations of acoustic focusing as applied to flow cytometry. © 2018 by John Wiley &amp; Sons, Inc.</p>","PeriodicalId":11020,"journal":{"name":"Current Protocols in Cytometry","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/cpcy.36","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36336632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detection of these potentially harmful complement-fixing HLA antibodies is commonly performed via the complement-dependent cytotoxicity (CDC) assay according to protocols that were developed as early as 40 years ago. The read-out for this assay is based on manual scoring by visual inspection of cells under a fluorescence microscope. CDC is often used in combination with the flow cytometry–based lymphocyte crossmatch assay (FCXM), which, with high sensitivity, detects HLA antibody binding. Here we describe a new approach wherein both cytotoxicity and antibody binding can be simultaneously assessed with flow cytometry. Two strategies are described, using either magnetic bead–enriched T and B lymphocytes or bulk peripheral blood mononuclear cells (PBMC) as donor target cells. <i>Curr. Protoc.

One of the most exciting applications of miniaturized chip-based cytometers is multivariate analysis using sampling volumes as small as 10 µl while matching the multiparameter data collection of conventional flow cytometers. We outline several innovative protocols for analyzing caspase-dependent cell death and cell cycle (DNA-content) profile using a fully integrated microfluidic flow cytometry system, Fishman-R. The first protocol describes the use of a new plasma membrane–permeability marker, DRAQ7, and the fluorogenic caspase substrate PhiPhiLux to track caspase activation during programmed cell death. Also outlined is the use of DRAQ7 fluorochrome in conjunction with the mitochondrial membrane potential–sensitive probe TMRM to track dissipation of inner mitochondrial cross-membrane potential. Another protocol adds the ability to measure dissipation of mitochondrial inner membrane potential (using TMRM probe) in relation to the cell cycle profile (using DRAQ5 probe) in living leukemic cells. Finally, we describe the combined use of fluorogenic caspases substrate PhiPhiLux with DRAQ5 probe to measure caspase activation in relation to the cell cycle profile in living tumor cells. <i>Curr.
