The FNLCR Molecular Histopathology Laboratory (MHL) provides comprehensive veterinary pathology support for animal health monitoring, biomarker discovery and validation, drug development, genomics, and proteomics on a cost recovered basis. The MHL is organized into multiple process groups with cross-trained experts in animal study design, phenotyping of genetically engineered mice (GEM), immunopathology, anatomic pathology, toxicological pathology, and specimen classification/selection for tissue microarray (TMA) construction or laser capture microdissection (LCM).
