Laboratory of Immunogenetics Pathology Core

Immunohistochemical analyses of a plasmacytic plasmacytoma, which show IRF 4 expressed in the cell nucleus, CD138 on cell membrane, and XBP1 in cytosols

The Pathology Core offers up-to-date expert support to NIAID intramural investigators by providing any and all research pathology-related services. These duties include preparation, diagnosis, and reporting of research pathology samples. In addition, the core provides collaborative advice in experimental design, performance, and interpretation of results, as well as assistance in manuscript preparation involving studies using laboratory animals, all aimed at validation of our animal pathology studies.

Collaborations with the LIG Pathology Core are available. Contact Dr. Chen-Feng Qi, Chief of Pathology Core. As a senior pathology research specialist with 20 years of human and research pathology experience, Dr Qi is leading the research Pathology Core to provide immediate, relevant, and useful services to all our staff members.
