Protocol Available protocols: Immunohistochemistry (Paraffin) Specificity / Sensitivity TMEM119 (E3E4T) Mouse Monoclonal Antibody recognizes endogenous levels of total TMEM119 protein. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human TMEM119 protein. Background Transmembrane protein 119 (TMEM119) is a cell-surface protein of unknown function, expressed exclusively by the microglia subset of myeloid and neural cells (1). Iba1+ microglia with both ramified and amoeboid morphologies express TMEM119, while Iba1+ macrophages are TMEM119 negative (2). and other homeostatic genes have been shown to be downregulated in disease-associated microglia (DAM). DAM are conserved in human and mouse and have been identified in Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and 5XFAD and APP/PS1 mouse models (3,4). This protein's specificity as a microglia marker has proven itself important for labeling microglia in healthy tissue as well as deciphering them from infiltrating macrophages and other cell types in neurodegenerative disease models (1,2).
