A) ELISA binding assay of purified 1B11 Fab to immobilized RTLs and four-domain recombinant MHC complexes. * indicates recombinant complexes that were compared only with RTL1000. Data are representative of three independent experiments B) Fab 1B11 detected RTL-like MHC class II material in serum and plasma samples from MS subjects and a pool of 3 healthy controls. Serum or plasma was collected prior to infusion of RTL1000 from MS Subjects #03–302, #04–402, #24, #40, #42 & #44 (0 time), from Subject #42 at 30min after initiating infusion of 200mg RTL1000; and #44 at 120min after initiating infusion of 100mg RTL1000. Differences between the samples and background were evaluated using two-tailed unpaired t-test. *p<0.05; **p<0.01; ***p<0.001.
Data are representative mean + SD of at least three independent experiments..
