Overview of Services







The Pathology Core Laboratory at the Research Institute at Children's Hospital of Philadelphia provides basic histopathology, research immunohistochemistry, tissue microarray, and digital slide scanning services to researchers at Children's Hospital of Philadelphia and within the surrounding academic community. We offer a full range of histopathology services for both paraffin-embedded and frozen tissue samples including tissue processing, embedding, and cutting. We also perform most standard stains as well as immunohistochemistry, antibody workup, fluorescence, in situ hybridization and TUNEL. Tissue microarrays can be constructed and our staining services may be used on slides acquired from the arrays. Sophisticated imaging instrumentation is available for both bright field and fluorescent microscopy including whole slide scanning. We also host specialized software to analyze, manage, and store data on stained tissues and arrays.

We are located in the A Level of Colket Tranlational Research Center (CTRB) in room A410. Daniel Martinez (267-426-5635 is the Lab Director and can address all questions regarding basic histopathology, research immunohistochemistry, tissue microarray and imaging. Dr. Ben Wilkinsoni, M.D./PhD. is the Faculty Director.
