INTENDED USE This Monkey ZBP1 ELISA kit is intended for laboratory research use only and not for use in diagnostic or therapeutic procedures. 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 Monkey ZBP1 in the sample, this Monkey ZBP1 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 Monkey ZBP1 concentration. The concentration of the samples is then determined by comparing the O.D. of the samples to the standard curve.
