For Samples: Cell culture fluid, body fluid, tissue homogenate, serum and blood plasma. Intended Uses: This LAM ELISA kit is intended for laboratory research use only and not for use in diagnostic or therapeutic procedures. The stop solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of LAM in the sample, this LAM ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus LAM concentration. The concentration of in the samples is then determined by comparing the O.D. of the samples to the standard curve. Principle of the Assay: The coated well immunoenzymatic assay for the quantitative measurement of LAM utilizes a multiclonal anti-LAM antibody and an LAM-HRP conjugate. The assay sample and buffer are incubated together with LAM-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the LAM concentration since LAM from samples and LAM-HRP conjugate compete for the anti-LAM antibody binding site. Since the number of sites is limited, as more sites are occupied by LAM from the sample, fewer sites are left to bind LAM-HRP conjugate. Standards of known LAM concentrations are run concurrently with the samples being assayed and a standard curve is plotted relating the intensity of the color (Optical Density) to the concentration of LAM. The LAM concentration in each sample is interpolated from this standard curve.
