ELISA of coated vasoinhibin and PRL with vasoinhibin-specific monoclonal antibodies. Four FDK-antibodies and seven HTS-antibodies were tested in a semi-quantitative indirect ELISA for their specificity to detect coated vasoinhibin in comparison to coated full-length PRL. The affinity of each antibody with vasoinhibin represented by its O.D. is plotted on the x-axis, and the affinity of each antibody with PRL by its O.D. on the y-axis, each antibody is indicated as a cross with mean and standard deviation, derived from triplicate measurements. The center point of each cross is the mean O.D. value of the triplicate measurement, and the lines show the range of the standard deviation. The green line represents the signal localization of the cross centers in case of equal affinity against vasoinhibin and PRL. The selected antibodies are shown in red. All tested antibodies are right of the green line toward the x-axis, which demonstrates a preference of vasoinhibin over PRL.
