Description
Intended Use: 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 ofA STREPTOCOCCAL POLYSACCHARIDE ANTIGENSin the sample, This A STREPTOCOCCAL POLYSACCHARIDE ANTIGENSELISA 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 versusA STREPTOCOCCAL POLYSACCHARIDE ANTIGENSconcentration. The concentration ofA STREPTOCOCCAL POLYSACCHARIDE ANTIGENSin the samples is then determined by comparing the O.D. of the samples to the standard curve
