Bielschowsky staining, immunofluorescence, and real-time PCR quality controls. (A1–4) Typical images of scores 0–3 in Bielschowsky silver staining. (B, C) Preabsorption assay for LINGO-1 and TROY in serial sections of chronic and acute phases, respectively (the phase where signal is most abundant). (B1) LINGO-1 antibody specifications: rabbit polyclonal, Abcam ab23631, LOT N/A, dilution 1:300. (B2) LINGO-1 peptide specifications: rabbit, Abcam ab25890, LOT #GR41007-1, incubation with ab in 10× molecular ratio. (C1) TROY antibody specifications: goat polyclonal, Santa Cruz sc-13711 (E-19), LOT #H0707, epitope mapping near the C-terminus of TROY of mouse origin, dilution 1:100. (C2) TROY peptide specifications: goat, Santa Cruz sc-13711 P, LOT #B0402, incubation with ab in 10× molecular ratio. (D, E) Antibody specificity test for p75 and NgR with the use of another antibody (different company) recognizing a different epitope in serial sections of chronic and acute phases, respectively (the phase where signal is most abundant). (D1) p75 antibody #1 specifications: mouse monoclonal, Abcam ab8877, LOT GR136825-1, ME20.4, dilution 1:400. (D2) p75 antibody #2 specifications: mouse monoclonal, Santa Cruz p75 (B-1) sc-271708, LOT #J0611, epitope mapping between amino acids 393–427 at the C-terminus of NGFR p75 of human origin, 1:100. (E1) NgR antibody #1 specifications: rabbit polyclonal, Santa Cruz sc-25659 (H-120), LOT E1209, epitope corresponding to amino acids 31–150 mapping near the N-terminus of Nogo-R of human origin, dilution 1:100. (E2) NgR antibody #2 specifications: rabbit polyclonal, Abcam ab26291, LOT N/A, epitope from within residues 150–250 of rat Nogo receptor, dilution 1:100. (F) β-actin real-time PCR quality control showing the specific amplification products on agarose gel and the melting curves of their respective genes; curve identifier: light green TROY, orange p75, dark green LINGO-1. (G) mRNA levels of coreceptors LINGO-1, p75, and TROY in the spinal cord of EAE animals by real-time PCR analysis using GAPDH as a second, quality control, house-keeping gene. The levels of mRNA expression for the coreceptors (G1) LINGO-1, (G2) p75, and (G3) TROY, followed the same pattern with those that underwent β-actin analysis. Error bars indicate the standard statistical error of the mean (SEM), ***p < 0.001, **p < 0.01. Black scale bar = 20 μm

Evidence of the production of anti-MOG-immunoglobulins within antisera when mice were inoculated with MOG peptide. (A) Purified EAE-AS (IgG from EAE-AS) and unpurified EAE-AS identified bands of the same molecular weight on NPCs substrate. Western blot of recombinant MOG as SDS-PAGE substrate (B) and ICC of EL4-MOG cells (C) revealed the real existence of anti-MOG-immunoglobulins within EAE-AS. One band was yielded (above 20kDA) when recombinant MOG was probed with EAE-AS and anti-MOG (positive control) (B). EAE-AS and anti-MOG showed high levels of binding on EL4-MOG cells (DAB staining), whereas NAIVE-AS did not bind (C). Magnification=40X, Scale=100Οm. (JPEG 344 kb
