Anti-HLA reactivity.
Anti-HLA reactivity (mean ± SD) of the median channel fluorescence values (n = 5) of the anti-HLA F(ab′)2fragments loaded onto the affinity columns (▵), and of bound proteins eluted from the affinity columns coated with F(ab′)2derived from (1) commercial IVIg (○), (2) sera from males (■), or (3) sera from multiparous women (●). The median channel fluorescence of phosphate-buffered saline only is shown (at x-axis = 0 [■]). The stars indicate significance (★: P < .01) between data points comparing proteins eluted from the affinity columns coated with F(ab′)2 derived from commercial IVIg versus from sera of multiparous women.
