Core Summary:

The Schepens Eye Research Institute of Mass. Eye and Ear (SERI) Morphology Core provides technical assistance and services for light, confocal, and electron microscopy. Priority will be given to SERI PI Researchers with NIH-NEI R01 Grants as we are principally funded through a NIH-National Eye Institute P30 Core Grant (P30EY003790). Routine histology sample preparation services include: Routine histological processing, sectioning and staining for frozen, paraffin, methacrylate and epoxy resin tissue preparations. Complete transmission electron microscopy (TEM) service includes; automated processing of tissue, semi-thin and thin sectioning of cell and tissue samples, TEM imaging and digital image acquisition (FEI Tecnai G2 Biotwin Spirit TEM with a AMT Camera) and scanning electron microscopy (JEOL JCM-7000 Neoscope SEM). The Core Facility Staff assists with technical problems, procedures, and training on instrumentation inclusive of; Ocular histology & electron microscopy protocols, cryostat sectioning, brightfield, fluorescence, confocal and electron microscopy. The SERI Morphology Core provides training on two Leica confocal microscopes (SP5 & SP8), Nikon Epifluorescent Microscopes, and a Leica LMD laser microdissection system for SERI Researchers. For PHS, External PHS Academic, and External Industry Clients please contact us with service requests prior to ordering with PCMS in order to potentially accommodate your needs.


  1. Technical assistance and sample preparation for light, electron, and confocal microscopy. Services include; frozen, paraffin, methacrylate, epoxy processing, sectioning and complete transmission/scanning electron microscopy services.
  2. Equipment resource, housing a laser microdissection system, two confocal microscopes (Leica SP5 & SP8 Inverted), automated histology and transmission electron microscopy tissue processors, ultramicrotomes, cryostats, various fluorescence and phase microscopes and printers to process digital images.
  3. Consultation for various histology, electron microscopy and microscopy procedures and troubleshooting, and training on all microscopes.
