Applications

Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human TREM‑1 Monoclonal Antibody (Catalog # MAB12781).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human TREM-1 DuoSet ELISA Kit (Catalog # DY1278B) for convenient development of a sandwich ELISA or the Human TREM-1 Quantikine ELISA Kit (Catalog # DTRM10C) for a complete optimized ELISA.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Human TREM‑1 ELISA Standard Curve. Recombinant Human TREM-1 protein was serially diluted 2-fold and captured by Mouse Anti-Human TREM-1 Monoclonal Antibody (Catalog # MAB12781) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human TREM-1 Monoclonal Antibody (Catalog # MAB12782) was biotinylated and 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: 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. The natural ligand for TREM-1 has not been identified. However, engagement of TREM-1 with an agonist 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. Human and mouse TREM-1 share approximately 42% amino acid sequence homology (1-3).
