Used in biomedical research to quantify soluble Triggering Receptor Expressed on Myeloid cells-1 (sTREM-1) in biological samples such as serum, plasma, and cell culture supernatants. It serves as a valuable tool for studying inflammatory conditions including sepsis, pneumonia, and other infectious or autoimmune diseases. Elevated levels of sTREM-1 are associated with activation of the innate immune system, making this kit useful for assessing inflammation severity and monitoring response to treatment in clinical and research settings. The assay enables early detection of bacterial infections and helps differentiate between infectious and non-infectious inflammation, supporting diagnostic development and therapeutic evaluation.
