FIG 3.

Negative sera have uniformly low absorbances. Box plot of delta OD (OD for FUS4 or FUS8 minus the OD for the c-myc backbone) from 1 positive-control (Pos) and 10 negative-control (Neg) plasma samples tested at a 1:25 dilution for 7S or 5.7S IgY antibody reactivity against FUS4 and FUS8 on seven ELISA plates over 3 days (four plates, day 1; three plates, day 2; two plates, day 3). The boxes represent the 25th and 75th percentiles, whiskers are 1.5 times the interquartile range, black dots are medians, and open circles are outliers.
