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). TMEM119 and other homeostatic genes have been shown to be downregulated in disease-associated microglia (DAM). These DAM microglia 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 cells types in neurodegenerative disease models (1,2).

Immunofluorescence Image 1: TMEM119 (E3E1O) Rabbit mAb Expand Image
Confocal immunofluorescent analysis of wild-type mouse brain (left) and liver (right) using TMEM119 (E3E1O) Rabbit mAb (green). Sections were mounted in ProLong® Gold Antifade Reagent with DAPI #8961 (blue).
Immunofluorescence Image 2: TMEM119 (E3E1O) Rabbit mAb Expand Image
Confocal immunofluorescent analysis of brain from an amyloid mouse model of Alzheimer’s disease. Sections were labeled with TMEM119 (E3E1O) Rabbit mAb (green) and GFAP (GA5) Mouse mAb #3670 (yellow). Plaques were then stained with β-Amyloid (D54D2) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate) #42284 (red) after blocking free secondary binding sites with Rabbit (DA1E) mAb IgG XP® Isotype Control #3900.
