This ELISA kit provides quantitative measurement of CXCL1 (GRO-α) in human samples, supporting research into neutrophil recruitment, inflammatory signaling, and tumor microenvironment biology. Because CXCL1 levels can vary dramatically between baseline circulation and acute inflammatory or tumor-associated states, the kit is designed to capture this dynamic range without extensive sample manipulation.
Detection Range: The 1.56–100 pg/mL range aligns with circulating CXCL1 concentrations typically observed in healthy human serum (low pg/mL) through moderately elevated levels in inflammatory conditions. Samples from acute sepsis, advanced tumors, or stimulated cell cultures may require dilution, as CXCL1 can exceed several hundred pg/mL in these contexts.
Sensitivity: At 0.78 pg/mL, the kit detects basal CXCL1 secretion from unstimulated endothelial or epithelial cell cultures and low-level expression in saliva or urine, where concentrations often fall below 10 pg/mL.
Sample Compatibility: Validation across serum, plasma, cell culture supernates, urine, saliva, and tissue homogenates enables researchers to correlate systemic CXCL1 levels with local tissue production and mucosal secretion within a single study—critical for mapping CXCL1 gradients that drive neutrophil chemotaxis.
Assay Efficiency: Requiring only 50–100 µL per well and 1–5 hours to complete, the kit accommodates limited-volume samples from primary human neutrophil or endothelial co-culture experiments and supports same-day data acquisition.
This kit is particularly suited for studies in CXCR2-axis-driven tumor progression, acute lung injury, and chronic inflammatory disease pathogenesis.
