(a) Natalizumab binding on VLA-4 expressing cells (PFSK1) compared with non-expressing cells (HEK293/T17) by flow cytometry using an FITC-conjugated secondary anti-IgG 4 . (b) Effect of natalizumab blocking antibody HCA250 on natalizumab and milk (T2) IgG 4 binding to PFSK1 cells. Serum was used at 1:40 dilution. Each column corresponds to average binding of IgG 4 on PFSK1 (geometric mean of the florescence intensity – GMFI – of cells incubated with the sample) from three replicates. Error bars are standard error. (c) Stability of expression of VLA-4 by PFSK1 cells. PFSK1 cells from passages 7 to 13 were incubated with either natalizumab at 10 µg/ml or with secondary only control. p -value for comparing binding of natalizumab to secondary only was calculated using unpaired t -test. Variances were compared using F -test. (d) Natalizumab detection in serum from treated patients positive for anti-natalizumab antibodies were compared with anti-natalizumab negative samples ( p < 0.0001, Mann–Whitney test) using an anti-IgG 4 antibody. Each dot corresponds to the binding of IgG 4 on PFSK1 (ratio of GMFI of cells incubated with the sample to cells incubated only with secondary antibody) from each serum sample, tested in three independent experiments.
