Anti-TREM-2 Antibody, clone 78

Description

• General description: TREM-2, also known as Triggering receptor expressed on myeloid cells 2 or Triggering receptor expressed on monocytes 2, and encoded by the gene Trem2/Trem2a/Trem2b/Trem2c, is a protein that forms a receptor signaling complex with TYROBP and triggers activation of the immune responses in macrophages and dendritic cells. TREM-2 may also have a role in chronic inflammations and may stimulate production of constitutive rather than inflammatory chemokines and cytokines. TREM-2 is localized to the cell membrane and is a single pass membrane protein. TREM-2 is expressed in immune cells such as microglia and monocytes but the expression varies depending upon the exact tissue and location within the tissue. Defects in TREM-2 may be associated in humans with frontotemporal dementia, Nasu-Hakola disease, and recently an increase risk of Alzheimer′s disease.
• Specificity: This antibody does not cross react with mouse TREM-1 or TREM-3 (Prof. William Seaman, University of California, San Francisco.).
• Immunogen: Recombinant protein corresponding to mouse TREM-2.
• Application: Immunocytochemistry Analysis: A representative lot from an independent laboratory detected TREM-2 in TRACP+ osteoclasts (Humprey, M. B., et al. (2006). J Bone Miner Res. 21(2):237-245.).Flow Cytometry Analysis: A representative lot from an independent laboratory detected TREM-2 in RAW264.7 cells (Humprey, M. B., et al. (2006). J Bone Miner Res. 21(2):237-245.). Immunoprecipitation Analysis: A representative lot from an independent laboratory immunoprecipitated TREM-2 from mouse macrophage lysates (Peng, Q., et al. (2010). Sci Signal. 3(122):ra38.).Inhibition Analysis: : Pre-treatment of BV2 cells or C57BL/6 Osteoclasts with a representative lot of this antibody significantly reduces cellular activation in response to both untreated and apoptotic Neuro2A cells (Hsieh, C. L., et al. (2009). J Neurochem. (109):4:1144-1156.; Humprey, M. B., et al. (2006). J Bone Miner Res. 21(2):237-245.).
• Quality: Evaluated by Western Blotting in human spleen tissue lysate.Western Blotting Analysis: 1 µg/mL of this antibody detected TREM-2 in 10 µg of human spleen tissue lysate.
• Target description: ~25 kDa observed. Uncharacterized band(s) may be observed in some cell lysates.
• Physical form: Format: Purified
• Storage and Stability: Stable for 1 year at -20°C from date of receipt.Handling Recommendations: Upon receipt and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
