The advantages of this mouse model compared to other animal models of laryngeal transplantation are its cost-effectiveness and the availability of immunologic assays and data. Cancer Research Manual Construction of a Tissue Microarray using the Tape Method and a Handheld Microarrayer Lee Wisner1, Brandon Larsen2, Alanna Maguire1 1Department of Research, Mayo Clinic, 2Department of Laboratory Medicine and Pathology, Mayo Clinic This protocol outlines the tape method on how to manually construct a tissue microarray using FFPE donor blocks of differing depths. Biology Enhancing Tumor Content through Tumor Macrodissection Lee Wisner1, Brandon Larsen2, Alanna Maguire1 1Department of Research, Mayo Clinic, 2Department of Laboratory Medicine and Pathology, Mayo Clinic This protocol presents a method to increase the percent tumor content of formalin-fixed paraffin-embedded tissue samples.
