This ELISA kit provides quantitative measurement of soluble ICAM-1 (sICAM-1/CD54) in mouse serum, plasma, and tissue homogenates, supporting immunological research into leukocyte adhesion and endothelial activation. Because sICAM-1 is shed from activated endothelium and immune cells during inflammatory responses, researchers need an assay calibrated to capture both baseline and inflammation-driven elevations across systemic and tissue-level compartments.
Detection Range: The 31.25–2000 ng/mL range spans the concentrations typically observed in mouse serum, where baseline sICAM-1 runs in the hundreds of ng/mL and rises substantially during acute inflammation or sepsis models. Most samples can be assayed neat or with minimal dilution, simplifying workflow for in vivo studies.
Sensitivity: At 15.6 ng/mL, the assay detects sICAM-1 in conditions where circulating levels are suppressed, such as immunodeficient strains or early time points following endothelial challenge.
Sample Compatibility: Validation across serum, plasma, and tissue homogenates allows researchers to correlate systemic sICAM-1 levels with local expression in inflamed organs—critical for models of lung injury, colitis, or graft rejection where tissue-specific endothelial activation drives pathology.
Assay Efficiency: Requiring only 50–100 µL per well and completable within 1–5 hours, the kit accommodates serial blood sampling from individual mice without exceeding safe collection volumes.
This kit is well suited for studies of LPS-induced endotoxemia, experimental autoimmune encephalomyelitis, and tumor immune microenvironment characterization.
