The Tufts confocal Microscope Facility is located within the Department of Anatomy and Cellular Biology and is in its fourth year of operation. Services are provided for receiving living or fixed samples labeled with 1-3 distinct fluorochromes with the most popular application being 3D reconstructions from optical sections, 2 or 3 overlay analysis for analyzing spatial proximity and improved spatial resolution with thick specimens. The fee-for-service facility provides training, various image processing/analysis opportunities, and hard copy output for publication or presentation purposes.

The Electron Microscope Applications Facility has become a university resource. as evidenced by its utilization by the Departments of Physiology, Microbiology, Neuroscience, NEMC Opthalmology, Surgical Research, Nephrology, Gastroenterology, Chemistry (Medford), the HNRC and MGH Surgery. It includes the Electron Microscopy Laboratory (M&V 142) and a Microscopy Suite (M&V 504) and as of 1999, has been directed by the very capable and talented duo of Cathy Linsenmayer and Liz Benecchi.

The Electron Microscope Laboratory us equipped to prepare materials for conventional transmission and scanning electron microscopy, and to provide such specialized techniques as immunoelectron microscopy using pre-embedding techniques and post-embedding approaches using ultra thin cryo sections which current users and staff routinely employ. The facility also supports molecular structure analysis and epitope mapping of antibody binding using electron microscopy of rotary shadowed and negatively stained preparations, and a variety of photographic procedures including printing of micrographs, production of plates for publication and slide preparation.

This fee-for-service is open to researchers in the Tufts Health Sciences Campus who wish to visualize their samples at the sub-cellular level.The facility offers support for fixation, embedding, sectioning, staining and microscope use

The Tufts Microscopy & Digital Image Analysis Facility is located within the Department of Anatomy and Cellular Biology. Services are provided for imaging bright-field, dark-field, phase-contrast, or fluorescently labeled samples. Current equipment inclues a Zeiss Axioscope and a high-resolution (1600 x 1200 pixels) Diagnostic Imaging Color Digital camera; a CCD video camera and Image Intensifier is also available for real-time biological imaging of live specimens. Quantitation of images may be done using OPTIMAS image analysis software which runs on a Pentium-III workstation.

The Tufts/NEMC Center for Gastroenterology Research on Absorptive and Secretory Processes (GRASP) was established in 1984 to promote research in digestive diseases on the Tufts Health Sciences Campus. Collaborating GRASP scientists are members of Departments of Tufts University Schools of Medicine and Veterinary Medicine, New England Medical Center Hospitals (NEMC), and the USDA Human Nutrition Research Center. GRASP has become the prototype of successful multi-disciplinary research interactions among investigators at the hospital and the Tufts health sciences schools. Despite the independence of these institutions, the Center has brought together basic and clinical scientists in a tightly coordinated and productive program. The GRASP Center consists of five Core Laboratories that service approximately 40 NIH funded investigators, whose studies represent the research base of the Center.

The Tufts DNA Sequencing, DNA Synthesis, and Peptide Synthesis Facility is located within the Department of Physiology. The DNA sequencing lab consists of three automated ABI 37X DNA sequencers. Each instrument runs 36 samples with a read length of 500-800 bases. The turnaround time is generally 2-3 days and the results are returned both as a text file via email and as a color chromatogram printout.The DNA synthesis service uses both an ABI 394 and an Expedite 8909. Together they can produce between 30 and 50 oligos each day. Two scales are available: 50nm and 200nm. Turnaround time is often within 24 hours. Oligos are shipped out dried down and quantitated and include a synthesis report. Cartridge purification is available but for most applications it is not necessary.The Peptide Synthesis Facility currently has three ABI 431 Peptide Synthesizers employing FastMoc Chemistry. We are capable of synthesizing 3-6 peptides per day depending on their lengths at 2 different scales: 0.1mm and 0.25mm. Turnaround time is usually between two to three weeks. All peptides are returned with a Mass Spec analysis and an analytical HPLC chromatogram with the exception of peptide libraries.

Tufts Center for Vision Research

The Center was launched in May of 2000 with the establishment of a partnership agreement between the New England Eye Center (Department of Ophthalmology) and the New England Medical Center/Tufts University. The Director of the TCVR, Dr. Elizabeth Fini, is a faculty member of the CMDB graduate program.

The mission of the Center is:

·        to support research/educational activities and shared resources for the 30 vision scientists on the Tufts campus,

·         to foster collaborative interaction among Tufts vision scientists, and between basic scientists and physician-scientists,

·        to attract well-trained people to do research on the visual system and its diseases. 

 

The TCVR currently supports four core resource modules:

·        Transgenic Mice: This institutional facility is directed by Dr. Janis Lem of the Department of Ophthalmology.  The department provides financial support for Dr. Lem’s research and career development, and has also provided much of the specialized equipment for the facility.  TCVR investigators have access to this facility along with other Tufts investigators.

·        Morphology: This module provides technical services, equipment resources, and technical advice to TCVR investigators.  There are two components: histology/light microscopy and confocal microscopy/electron microscopy.  The first component is housed in the 75 Kneeland Street labs, the second component is part of the core facilities of the Department of Anatomy and Cellular Biology, within the Medical and Veterinary complex.  The directors of this module, Drs. Dale Hunter and Judith West-Mays, are CMDB program faculty members.

·        Monoclonal Antibodies and Tissue Resources: This module provides technical services, equipment resources, and technical advice to TCVR investigators.  In addition, human eye tissues are provided to investigators through the ophthalmology clinical services of the New England Eye Center.

·        Computational Biology Module:  Recently, the rough draft of the human genome sequence was completed.  TCVR investigators wish to take advantage of this wealth of new information for their research.  This module provides a collaborative resource for bioinformatics, data management, and biostatistics.  In addition, the module provides computer hardware and software support, and computer resources.  The module is directed by Dr. Elizabeth Fini, a CMDB program faculty member.  The module is staffed by computational geneticist Dr. Kurt Wollenberg.  The module has a partnership arrangement with the Center for Biostatistics Research, Division of Clinical Care Research, Department of Medicine.

 

Informal and formal seminar series in Vision Science--------A variety of mechanisms are utilized by the Center for bringing the vision scientists together for scientific interchange. The Vision Research Laboratories Conference, a research-in-progress series, holds monthly meetings in the conference room on the 12th floor of 75 Kneeland Street, but it is planned to change this to a lunch-time seminar in the next year, to be held in the auditorium at the ophthalmology clinic.  The Ophthalmology Department has been hosting a high profile seminar series, Frontiers in Vision Science.  This series has brought a number of prominent Vision Scientists to Tufts over the years, most recently in 1997.  Plans are in progress for another iteration of the series beginning in January 2001, this time sponsored by the TCVR. The Ophthalmology Residents and Fellows education program of Morning Conferences and Grand Rounds is open to all Vision Scientists.  An Opthalmology Basic Science Conference was formally incorporated into this program in 1998. The conference focuses on pathophysiological mechanisms in eye diseases and features lectures from an outside speaker, or from one of the Tufts vision researchers.  These meetings are held in the Ophthalmology clinic auditorium on the 10th floor of the Biewend building.
