Histopathology Core

Overview of Services


The Histopathology Core provides services in histology and routine transmission electron microscopy (TEM).


The histology section of the core is accredited by the College of American Pathologists (CAP). It provides basic services such as tissue preparation and embedding, paraffin block or frozen tissue sectioning, and H&E staining. The core provides additional services such as direct and indirect immunohistochemical staining, selected histochemical stains, serial sectioning and RNase-free handling. Core personnel have extensive experience in tissue microarray construction. The lab is equipped with a Perkin-Elmer TMA Master automated TMA arrayer as well as two MTA-1 manual Beecher TMA arrayers. 


Routine TEM procedures such as fixation, embedding, sectioning, and visualization are available. The core utilizes a Hitachi H-7650 Transmission Electron Microscope (TEM) with two digital cameras. Magnification ranges from 0.7K up to 200K. The imaging software is AMtv542.
