Product Summary
The Quantikine Human TREM-1 Immunoassay is a 4.5 hour solid phase ELISA designed to measure TREM-1 levels in cell culture supernates, cell lysates, serum, plasma, and saliva. It contains NS0-expressed recombinant human TREM-1 and antibodies raised against the recombinant protein. Results obtained for naturally occurring human TREM-1 showed linear curves that were parallel to the standard curves obtained using the Quantikine Human TREM-1 Immunoassay standards. These results indicate that this kit can be used to determine relative mass values for natural human TREM-1.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components

Recovery

The recovery of human TREM-1 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 102 94-112
Cell Lysis Buffer (n=4) 88 78-96
EDTA Plasma (n=4) 99 92-105
Heparin Plasma (n=4) 96 87-104
Serum (n=4) 97 84-107
Linearity
To assess the linearity of the assay, samples spiked with high concentrations of human TREM-1 were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: TREM-1
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.
