Flow and Imaging Cytometry Core Facility | NINDS Division of Intramural Research

Background

The Flow & Imaging Cytometry Core Facility provides intellectual, technical, training and collaborative support to NINDS and other intramural.

investigators in both basic and clinical research programs requiring seamless and productive use of conventional flow cytometry, imaging flow cytometry, preparative fluorescence-activated cell sorting (FACS) and in situ cytometric imaging techniques to assay cell biology at the molecular, subcellular and cellular levels, as specified by the investigator. Depending on the investigator's requirements, the Facility provides high-throughput screening of cells and assaying of their specific biological properties, in addition to preparative sorting of purified cell populations and/or subpopulations of interest, based on one of more specific cellular/subcellular parameters, as specified by the investigator.

Facility staff is also continuously engaged in research and development of novel methodological approaches to comprehensively study systems biology in the brain using animal models for specific neurological and neurodegenerative disorders (ischemic and traumatic brain injuries, brain tumors, aging brain, select transgenic animal models of neurodevelopmental and neurodegenerative diseases, etc.), for which they combine up to 100-plex biomarker immunohistology screening with multi-spectral fluorescence imaging and multi-parametric big image data analyses.

Scope of the Core Facility

The primary mission of the Facility is to provide intellectual, technical, collaborative and new application research and development support to NINDS and other intramural investigators in both basic and clinical research programs requiring the use of high-throughput conventional flow cytometry (CFC), imaging flow cytometry (IFC), preparative fluorescence-activated cell sorting (FACS) and multi-spectral in situ cytometric imaging (ISCI). The Facility currently provides routine use of CFC, IFC, FACS and ISCI applications in assaying a multitude of biological properties at the cellular, subcellular and molecular levels, as specified by the investigator.

Critical to these activities is the research and development of a wide variety of novel, customized and standardized multiplex biomarker screening protocols using unique combinations of fluorescent reporters of interest, including those identifying different stages of cell proliferation and differentiation, as well as different types of cell death (i.e., apoptotic, necrotic, cytotoxic, autophagy), in addition to those assaying functional gene expression and cell signaling. The aim of these protocols is to maximize the simultaneous detection and quantification of multiple biological properties per cell and its subcellular compartments (i.e., plasma membrane, cytoplasm, nucleus, mitochondria, lysosomes, synaptosomes, microvesicles, exosomes), utilizing an array of appropriate cell surface, cytoplasmic, nuclear, protein and gene expression biomarkers, as well as select physiological indicator dyes (potentiometric, calcium, pH, live/dead), linked to fluorescent endpoints.

Depending on the investigator’s requirements, the Facility provides high-throughput screening of cells and assaying of their specific biological properties, in addition to preparative sorting of purified cell populations and/or subpopulations of interest, based on one or more specific cellular/subcellular parameters, as specified by the investigator. Additional responsibilities of the Facility personnel include regular maintenance and technological upgrades of all instruments that are managed by the Facility, as well as daily instrument alignment and calibration, setting up sample quality controls and standardization, and enabling seamless data acquisition and analysis, presentation and interpretation of the resulting findings to the investigator, and, if requested by the investigator, manuscript preparation and critical review.

How to Use the Core Facility

To schedule an appointment, please contact the Core Director by e-mail (maricd@ninds.nih.gov), phone (301-402-1406) or stop by the Core Facility (Building 10, Room 5S-241) to sign in the scheduling calendar. If new to flow and imaging cytometry or unsure how to best utilize the resources available at the Core, the Core Director will be available to assist the investigator using the following workflow:

Step 1 - Initial consultation with initiating investigator to determine optimal experimental designs tailored to investigator’s interests. The investigator is also familiarized with all the bioassays that have been standardized and are routinely available at the Core Facility.

Step 2 - If standard bioassays currently provided by the Core are not adequate, the Core Director will work with the investigator to conduct new research and development of customized applications to meet the investigator’s requirements.

Step 3 - Pilot experiments are carried out first to empirically optimize the bioassays using quality controls for verifying sample integrity and identifying specific endpoints of fluorescent reporters, while at the same time discriminating against possible artifacts and non-specific signals.

Step 4 - Once optimized and standardized, the bioassays are available to the investigator for routine use. If problems are encountered with the instrumentation, samples or bioassays, the Core Director will be available to troubleshoot the problems and provide optimal solutions to correct the problems.
