Welcome to the PMB Microscopy Core

The Microscopy Core of the Program in Membrane Biology (PMB) at MGH is equipped and staffed to provide a wide range of services to investigators from MGH and the Boston area scientific community in the area of light and electron microscopy. The Core is housed on the 8th floor of the Simches Research Center at MGH, and is directed by Dr. Dennis Brown, Ph.D. The Core will provide services ranging from the complete performance of the technical procedures required, to full training of personnel. Among the techniques available are laser scanning confocal microscopy, spinning disk confocal microscopy, tissue fixation, sectioning, immunostaining and conventional immunofluorescence microscopy, image analysis, and all aspects of electron microscopy including immunogold staining. The Core Facility provides a unique and important resource for members of the scientific community as they approach a variety of research problems that call for these advanced microscopy techniques.

Services:

1. Technical Services
The core will perform conventional immunofluorescence microscopy, confocal microscopy, live-cell imaging, conventional electron microscopy and EM immunogold labeling, tissue sectioning, tissue fixation, and computer-based image analysis and quantification. In some cases, investigators will provide their own stained tissues/cell for imaging, while in others the Core will perform all services from fixation and sectioning, to staining and imaging.
2. Training Services
The core technicians will also provide training to high-frequency users who wish to invest the substantial time necessary for learning to use the equipment proficiently (with the exception of the electron microscope).
3. Consultation Services
Core personnel will be available for consultation in the use of the different microscopy techniques, and to provide technical advice, such as the different fixation techniques that enable antibodies to detect their antigens, data analysis, experimental design, etc.
4. Development for Core Enhancement 
Dr. Dennis Brown and the advisory committee will continually explore new techniques to be offered as part of the core service.
