Target description

Triggering receptor expressed on myeloid cells 2 (UniProt: Q9NZC2; also known as TREM-2, Triggering receptor expressed on monocytes 2) is encoded by the TREM2 gene (Gene ID: 54209) in human. TREM-2 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 19-174), a transmembrane domain (aa 175-195), and a cytoplasmic domain (aa 196-230). TREM-2 is an Ig-like V-type receptor expressed by populations of myeloid cells in various region of the central nervous system. In the CNS strongest expression seen in the basal ganglia, corpus callosum, medulla oblongata and spinal cord. Its expression is also reported on macrophages and dendritic cells, but not on granulocytes or monocytes. TREM-2 is highly expressed in microglia, where it, along with its adaptor protein DAP12, regulates inflammatory cytokine release and phagocytosis of apoptotic neurons. It plays a role in chronic inflammations and may stimulate production of constitutive rather than inflammatory chemokines and cytokines. Its short cytoplasmic tail does not contain any signaling motifs and relies on its association with the immunoreceptor tyrosine-based activation motif- (ITAM-) containing TYROBP for signal transduction. It forms a receptor signaling complex with TYROBP and triggers activation of the immune responses in macrophages and dendritic cells. Apolipoprotein E (ApoE) is reported to function as a high-affinity ligand for TREM-2. ApoE binding is shown to enhance the phagocytosis of apoptotic Neuro2a cells by primary microglia cells. Greatly reduced ApoE binding is seen with Alzheimer s disease-associated TREM-2 R47H mutant. TREM2 gene mutations and polymorphisms have been linked to several neurological disorders, including Alzheimer s disease (AD), frontotemporal dementia (FTD), Parkinson s disease (PD), and Nasu-Hakola disease. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
