Columbia Advanced Tissue Pathology and Imaging Core


The Advance Tissue Pathology and Imaging Core provides a spectrum of advanced cellular and tissue pathology and imaging services that meet the needs of diabetes researchers at Columbia University. The Core also provides state-of-the-art microscopy equipment and services. They include confocal, live 2-photon and scanning & transmission electron microscopy. As more advanced and specialized microscopy services have been added, the ATPI Core has added relevant technical training and provided requisite image acquisition and analysis capabilities.
