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 ofTRANSFORMING GROWTH FACTOR beta4in the sample, This TRANSFORMING GROWTH FACTOR beta4ELISA 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 versusTRANSFORMING GROWTH FACTOR beta4concentration. The concentration ofTRANSFORMING GROWTH FACTOR beta4in the samples is then determined by comparing the O.D. of the samples to the standard curve
