General description

TREM2 (triggering receptor expressed on myeloid cells 2) belongs to the immunoglobulin (Ig) family, and is a transmembrane receptor. It has an extracellular region containing the Ig-like domain and has a cytoplasmic tail. TREM2 protein is composed of 230 amino acids, which consists of a signal peptide of 13 amino acids, 154 amino acids extracellular region, a transmembrane region of 33 amino acids succeeded by a cytoplasmic tail of 30 amino acids. This gene is localized to human chromosome 6p21.1. It is expressed on myeloid cells such as, macrophages found in tissue and dendritic cells. It is also expressed on microglial cells in brain, which are the predominant innate neuroimmune cells.


Triggering receptor expressed on myeloid cells 2 precursor recombinant protein epitope signature tag (PrEST)


Anti-TREM2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

TREM2 (triggering receptor expressed on myeloid cells 2) performs phagocytosis of bacteria and is involved in regulation of inflammatory responses. As it is expressed on microglia, it is responsible for the clearance of neural debris on microglia. Microglia is responsible for the phagocytosis, degradation and clearance of Amyloid β peptide (Aβ) in brain. TREM2 suppresses the ability of microglia to phagocytize Aβ, and disturbs the pro-inflammatory activity of these cells. Parkinson′s disease (PD) is characterized by the degeneration of dopaminergic neurons, in the substantia nigra pars compacta region of the brain. TREM2 binds directly to the ligands expressed by these dopaminergic neurons. Also, microgliosis is also involved in the progression of PD. Therefore, variations in TREM2 gene might be linked to susceptibility to PD. p.R47H polymorphism in this gene is related to increased risk of sporadic amyotrophic lateral sclerosis. Mutations in this gene are also linked with polycystic lipomembranous osteodysplaysia with sclerosing leukoencephalopathy.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
• Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)
