Advanced Imaging Core

Ronald S. Petralia, Ph.D., Staff Scientist


The Advanced Imaging Core (AIC) offers investigators specialized centralized core laboratory support services. The primary goal of the AIC is to support the research interests and ongoing projects of various NIDCD laboratories within the Division of Intramural Research (DIR).  The AIC provides the resources necessary to assist in the proper performance of a variety of specialized experiments and in the interpretation of obtained data. The AIC provides specific expertise, new technologies, and resources to enhance the research efforts of all NIDCD investigators. The team specializes in transmission electron microscope (TEM) studies of immunocytochemistry and ultrastructure, but can also do scanning electron microscopy (SEM).

Cell biological studies, including physiology, genetics, immunocytochemistry, etc., always consider what happens at the molecular level. Transmission electron microscopy allows scientists to come closer than ever to studying cell composition at the molecular level. The AIC’s TEM specialists offer training and related assistance to principal investigators at the NIDCD, and contribute to collaborative studies with scientists at the NIDCD, NIH, and beyond.
