The Quantikine Mouse/Rat TREM-1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse or rat TREM-1 in cell culture supernates, tissue homogenates, serum, and plasma. It contains E. coli-expressed recombinant mouse TREM-1 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural TREM-1 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring TREM-1.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
The recovery of TREM-1 spiked to levels throughout the range of the assay in various matrices was evaluated.

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of TREM-1 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
The TREM family of receptors regulates the activity of various cell types of the immune system including neutrophils, monocyte/macrophages, microglia, and dendritic cells. The receptors are members of the immunoglobulin superfamily, characterized structurally by a single V-set immunoglobulin (Ig) domain and a short cytoplasmic tail. TREMs associate with the DAP12 signal adapter, an immunoreceptor tyrosine-based activation motif- (ITAM)-containing protein that is phosphorylated and transduces signals when activated.
