Electron Microscopy (EM) Facility

Headed by Dr. Chris Goulbourne, the electron microscopy (EM) facility is a core facility that provides EM service to investigators. The facility houses an ThermoFisher Talos L120C TEM that has the capability to do 2D imaging, dual axis electron tomography for 3D ultrastructural evaluation and cryo EM. Services offered include ultrastructural evaluation in 2D and 3D, protein localization using immunogold techniques and cryogenic evaluation of proteins, viruses and cellular architecture. Additionally, the facility offers advice and sample preparation for employing correlative light and electron microcopy(CLEM) and Nano Secondary Ion Mass spectrometry (NanoSIMS) for tracking stable isotope tagged molecules. Sample preparation instrumentation includes a Leica UCT ultramicrotome and ThermoFisher Mark IV Vitrobot. We have a dedicated high performance work station for processing 3D data sets using Amira and Imod software. The services of the facility are currently available to external academic institutes and industrial facilities on a fee-for-use-basis. Further information can be obtained by contacting Dr. Chris Goulbourne at Chris.Goulbourne@NKI.rfmh.org

The FEI Talos L120C TEM has magnification between 25X upto 650,000x and 0.2nm line resolution. Capabilties include electron tomography for 3D ultrastructural evaluation, regular 2D imaging and cryoelectron microscopy.
The FEI Vitrobot Mark IV is used for cryo sample preparation of cells, exosomes, proteins and viruses. The Leica Reichert Ultracut S microtome with Diatome diamond knife for sectioning samples between 60 to 1000nm.
The PELCO easiGlow is used to glow discharge grids to make them hydrophilic for even sample distribution. The LKB knife maker is used to make glass knives for preparing the sample block face. Dedicated high performance computer workstation for processing and visualizing tomographic data sets. Used for visualising cellular ultrastructure in 3D.

NKI Health Sciences Library

Under library director, Stuart Moss, MLS, the Health Sciences Library of the Nathan Kline Institute offers an extensive array of mental health and biomedical information resources in both print and electronic formats. The research-oriented collection is particularly strong in psychiatry, neuroscience, and psychopharmacology. It includes over 300 current journal subscriptions, more than 25,000 bound journal volumes and books, as well as access to the entire MEDLINE and PsycINFO databases, and toNOVEL, the New York Online Virtual Electronic Library. The NKI Library is one of the best sources for psychiatric information in the Hudson valley region.

Center for Biomedical Imaging and Neuromodulation (C-BIN)

Known (formerly CABI) has yielded the first images of the brain in transgenic mice modeling the pathology of Alzheimer’s disease. The sensitive detection of pathology in animal models has MRIprovided the basis for new neuro-imaging approaches to characterize patients with mild cognitive impairment or AD. The approximately 12,000 sq. ft. facility is centered around the technology of Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy (MRS) and houses three state-of-the-art MR systems. Headed by Michael Milham, MD, PhD, C-BIN is divided into the Computational Neuroimaging Laboratory; Design, Acquisition and Stimulation Laboratory (DASL); and Medical Physics Laboratory (MPL). These subdivisions work together to understand the impact of psychiatric illnesses on developmental processes utilizing innovative MRI-based imaging approaches to characterize brain maturation across the lifespan.


Genomics Facility

The Genomics Facility at the Nathan Kline Institute has state-of-the-art instrumentation for molecular and cellular based operations, including single population cellular analyses. Dr. Ginsberg oversees the instrumentation that includes a new laser capture microdissection (LCM) system (Leica LMD 7000) which enables precise microaspiration of neurons and other cells fromLMC tissue sections. This instrumentation is critical for analyses at the NKI of vulnerable and relatively spared populations of neurons in neurodegenerative disorders including Alzheimer's disease (AD) and Down syndrome (DS), among others. Cells can be isolated from a wide variety of cell culture, animal model, and human postmortem brain tissue preparations. The NKI Genomics Facility also houses qPCR instrumentation and robotics for the generation of custom-designed microarray platforms. Please feel free to contact Dr. Ginsberg if you are interested in learning more about the instrumentation or the experiments that are conducted using these tools.
