Human Lactalbumin Alpha ELISA Kit (Colorimetric)

The stop solution changes 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 Human Lactalbumin Alpha in the sample, this Human Lactalbumin Alpha 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 Human Lactalbumin Alpha concentration. The concentration of the samples is then determined by comparing the O.D. of the samples to the standard curve.
