Human Leukocyte Elastase Inhibitor ELISA Kit from Innovative Research is intended for the quantitative determination of Human Leukocyte Elastase Inhibitor in biofluid samples, such as serum, plasma, tissue homogenates and other biological fluids. This is a sandwich ELISA in strip well format with reagents for up to 96 tests . LEI present in samples reacts with an anti-Human LEI capture antibody coated and dried on a microtiter plate. After appropriate washing steps, an anti-LEI detection antibody conjugated to biotin binds to the captured analyte. Excess antibody is washed away and bound antibody is then reacted with avidin conjugated to horseradish peroxidase. TMB substrate is used for color development at 450nm. Color development is directly proportional to the concentration of active LEI in the samples. A standard calibration curve is prepared along with the samples to be measured using dilutions of Human LEI. Detection Target: Human Leukocyte Elastase Inhibitor Reactivity: Human Range: 0.312-20ng/mL Sensitivity: 0.117ng/mL Storage Conditions: Store all components at 4┬░C This Human LEI activity assay is for the quantitative determination of Leukocyte Elastase Inhibitor in samples including serum, plasma, tissue homogenates and other biological fluids. For research use only. Strip well format. Reagents for up to 96 tests. For research use only. At Innovative Research, we provide reliable, consistent products that deliver reliable, consistent results.
