Scientific Data Images for Mouse TREM-1 Antibody

Detection of TREM‑1 in Mouse Splenocytes by Flow Cytometry.

Mouse splenocytes were stained with Rat Anti-Mouse Gr-1/Ly-6G Alexa Fluor® 405-conjugated Monoclonal Antibody (Catalog # FAB1037V) and either (A) Rat Anti-Mouse TREM-1 Monoclonal Antibody (Catalog # MAB1187) or (B) Rat IgG_2AIsotype Control (Catalog # MAB006) followed by Phycoerythrin-conjugated Anti-Rat IgG Secondary Antibody (Catalog # F0105B).

TREM-1 in Mouse Splenocytes.

TREM-1 was detected in immersion fixed mouse splenocytes treated with LPS using Rat Anti-Mouse TREM-1 Monoclonal Antibody (Catalog # MAB1187) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: TREM-1

TREM-1 (Triggering Receptor Expressed on Myeloid cells) is a type I transmembrane protein having a single Ig-like domain. It associates with the adapter protein, DAP12, to deliver an activating signal. Several other TREM family members have been reported that are structurally similar but share less than 30% amino acid identity. TREM-1 is expressed on blood neutrophils and a subset of monocytes, and expression is up-regulated by bacterial LPS. Engagement of TREM-1 with a monoclonal antibody leads to expression of IL-8, MCP-1, and TNF-alpha suggesting that this receptor plays an important role in inflammatory responses. TREM-1 is expressed at high levels on neutrophils of patients with microbial sepsis and in mice with LPS-induced shock. Blockade of TREM-1 with a TREM-1/Fc fusion protein protected mice against LPS-induced shock.
