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 ofPREGNANCY ASSOCIATED PLASMA PROTEIN A2in the sample, This PREGNANCY ASSOCIATED PLASMA PROTEIN A2ELISA 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 versusPREGNANCY ASSOCIATED PLASMA PROTEIN A2concentration. The concentration ofPREGNANCY ASSOCIATED PLASMA PROTEIN A2in the samples is then determined by comparing the O.D. of the samples to the standard curve
