Immunocytochemistry View Larger

TREM2 Specificity is Shown by Immunocytochemistry in Knockout Cell Line. Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) was detected in immersion fixed RAW 264.7 mouse monocyte/macrophage cell line but is not detected in TREM2 knockout (KO) RAW 264.7 Mouse Cell Line cell line using Rat Anti-Human/Mouse TREM2 Monoclonal Antibody (Catalog # MAB17291) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.Staining was performed using our Fluorescent ICC Staining of Cells on Coverslips.

Mouse TREM2 ELISA Standard Curve. Recombinant Mouse TREM2 protein was serially diluted 2-fold and captured by Rat Anti-Human/Mouse TREM2 Monoclonal Antibody (Catalog # MAB17291) coated on a Clear Polystyrene Microplate (Catalog # DY990). Sheep Anti-Mouse TREM2 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF1729) was incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: TREM2

TREM2 (Triggering Receptor Expressed on Myeloid cells-2) is a 35 kDa molecular weight type I transmembrane member of the TREM family and Ig superfamily. Mature human TREM2 consists of a 156 amino acid (aa) extracellular domain (ECD) with one V-type Ig-like domain, a 21 aa transmembrane (TM) domain, and a 35 aa cytoplasmic tail. Within the ECD, human TREM2 shares 73% and 74% aa sequence identity with mouse and rat TREM2, respectively. Two closely related transcripts were reported in mouse and designated TREM2a and TREM2b. Soluble forms of the TREM2 ECD are generated by alternative splicing or proteolytic cleavage, and the cytoplasmic domain can be liberated by gamma-Secretase mediated intramembrane cleavage. It is a pattern recognition receptor that binds anionic ligands. A positively charged lysine within the transmembrane segment allows association with the signal adapter protein, DAP12 to deliver an activating signal that plays a role in both innate and adaptive immune responses, including inhibition of macrophage activation. TREM2 is expressed on macrophages, immature myeloid dendritic cells, osteoclasts, microglia, and adipocytes. It promotes the differentiation and function of osteoclasts, the production of inflammatory cytokines by adipocytes, insulin resistance, and the phagocytic clearance of bacteria. In the CNS, TREM2 binds to ApoE, ApoA1, and ApoB and mediates the clearance of apoptotic neurons, amyloid plaques, and cell debris following demyelination. TREM2 also interacts with and modifies signaling through Plexin A1 on dendritic cells and osteoclasts. Mutations in TREM2 or DAP12 are associated with the development of Alzheimer's disease and Nasu-Hakola disease (NHD/PLOSL) which is characterized by presenile dementia and bone cysts. Soluble TREM2 is elevated in cerebrospinal fluid of patients with active multiple sclerosis (MS), and TREM2 blockade exacerbates disease symptoms in the experimental EAE model of MS.
