Figure 1. Umbilical cord blood titer of anti-p200, anti-Ro52, anti-Ro60 and anti-La.

Figure 1

Reactivity of umbilical cord plasma from neonates with cardiac NL (Group 1), unaffected siblings of neonates with cardiac NL (Group 2), or unaffected neonates with only unaffected siblings (Group 3) against p200 (Ro52 aa 200–239) peptide (A), full length recombinant Ro52 (B), native Ro60 (C), or native La (D). The mean ELISA binding units of duplicate determinations is plotted for each neonate that was considered positive (>3 SD above the median binding units for 28 healthy controls). Cut-offs for positivity are >6.4 for Ro52, >4.5 for p200 and >19 for Ro60 and La. Solid lines represent the median ELISA binding units for each group.
